Part 1 Change Log (Non-Normative) E.1 WSDL 2.0 Specification Changes ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Introduction Web Services Description Language Version 2.0 (WSDL 2.0) provides a model and an XML format for describing Web services. WSDL 2.0 enables one to separate the description of the abstract functionality offered by a service from concrete details of a service description such as “how” and “where” that functionality is offered. This specification defines a language for describing the abstract functionality of a service as well as a framework for describing the concrete details of a service description. It also defines the conformance criteria for documents in this language. The WSDL Version 2.0 Part 2: Adjuncts specification [WSDL 2.0 Adjuncts] describes extensions for Message Exchange Patterns, features, SOAP modules and bindings of features, and a language for describing such concrete details for SOAP 1.2 [SOAP 1.2 Part 1: Messaging Framework] and HTTP [IETF RFC 2616]. 1.1 Web Service WSDL 2.0 describes a Web service in two fundamental stages: one abstract and one concrete. Within each stage, the description uses a number of constructs to promote reusability of the description and to separate independent design concerns. At an abstract level, WSDL 2.0 describes a Web service in terms of the messages it sends and receives; messages are described independent of a specific wire format using a type system, typically XML Schema. An operation associates a message exchange pattern with one or more messages. A message exchange pattern identifies the sequence and cardinality of messages sent and/or received as well as who they are logically sent to and/or received from. An interface groups together operations without any commitment to transport or wire format. At a concrete level, a binding specifies transport and wire format details for one or more interfaces. An endpoint associates a network address with a binding. And finally, a service groups together endpoints that implement a common interface. 1.2 Document Conformance An element information item (as defined in [XML Information Set]) whose namespace name is "http://www.w3.org/2005/08/wsdl" and whose local part is description conforms to this specification if it is valid according to the XML Schema for that element as defined by this specification (http://www.w3.org/ 2005/08/wsdl/wsdl20.xsd) and additionally adheres to all the constraints contained in this specification family and conforms to the specifications of any extensions contained in it. Such a conformant element information item constitutes a WSDL 2.0 document. The definition of the WSDL 2.0 language is based on the XML Information Set [ XML Information Set] but also imposes many semantic constraints over and above structural conformance to this XML Infoset. In order to precisely describe these constraints, and as an aid in precisely defining the meaning of each WSDL 2.0 document, the WSDL 2.0 specification defines a component model 2. Component Model as an additional layer of abstraction above the XML Infoset. Constraints and meaning are defined in terms of this component model, and the definition of each component includes a mapping that specifies how values in the component model are derived from corresponding items in the XML Infoset. An XML 1.0 document that is valid with respect to the WSDL 2.0 XML Schema and that maps to a valid WSDL 2.0 Component Model is conformant to the WSDL 2.0 specification. 1.3 The Meaning of a Service Description A WSDL 2.0 service description indicates how potential clients are intended to interact with the described service. It represents an assertion that the described service fully implements and conforms to what the WSDL 2.0 document describes. For example, as further explained in section 6.1.1 Mandatory extensions, if the WSDL 2.0 document specifies a particular optional extension, the functionality implied by that extension is only optional to the client. But it needs to be supported by the Web service. A WSDL 2.0 interface describes potential interaction with a service--not required interaction. The declaration of an operation in a WSDL 2.0 interface is not an assertion that the interaction described by the operation must occur. Rather it is an assertion that if such an interaction is (somehow) initiated, then the declared operation describes how that interaction is intended to occur. 1.4 Notational Conventions All parts of this specification are normative, with the EXCEPTION of notes, pseudo-schemas, examples, and sections explicitly marked as “Non-Normative”. 1.4.1 RFC 2119 Keywords The keywords “MUST”, “MUST NOT”, “EQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119 [IETF RFC 2119]. 1.4.2 RFC 3986 Namespaces Namespace names of the general form: • "http://example.org/..." and • "http://example.com/..." represent application or context-dependent URIs [IETF RFC 3986]. 1.4.3 Prefixes and Namespaces Used in This Specification This specification uses predefined namespace prefixes throughout; they are given in the following list. Note that the choice of any namespace prefix is arbitrary and not semantically significant (see [XML Namespaces]). wsdl "http://www.w3.org/2005/08/wsdl" Defined by this specification. wsdli "http://www.w3.org/2005/08/wsdl-instance" Defined by this specification 7.1 wsdli:wsdlLocation attribute information item. wsdlx "http://www.w3.org/2005/08/wsdl-extensions" Defined by this specification 3.3 Describing Messages that Refer to Services and Endpoints. wrpc "http://www.w3.org/2005/08/wsdl/rpc" Defined by WSDL 2.0: Adjuncts [WSDL 2.0 Adjuncts]. wsoap "http://www.w3.org/2005/08/wsdl/soap" Defined by WSDL 2.0: Adjuncts [WSDL 2.0 Adjuncts]. whttp "http://www.w3.org/2005/08/wsdl/http" Defined by WSDL 2.0: Adjuncts [WSDL 2.0 Adjuncts]. xs "http://www.w3.org/2001/XMLSchema" Defined in the W3C XML Schema specification [XML Schema: Structures], [XML Schema: Datatypes]. xsi "http://www.w3.org/2001/XMLSchema-instance" Defined in the W3C XML Schema specification [XML Schema: Structures], [XML Schema: Datatypes]. 1.4.4 Terms Used in This Specification This section describes the terms and concepts introduced in Part 1 of the WSDL Version 2.0 specification (this document). Actual Value As in [XML Schema: Structures], the phrase actual value is used to refer to the member of the value space of the simple type definition associated with an attribute information item which corresponds to its normalized value. This will often be a string, but may also be an integer, a boolean, a IRI reference, etc. Inlined Schema An XML schema that is defined in the xs:types element information item of a WSDL 2.0 description. For example, an XML Schema defined in an xs:schema element information item 3.1.2 Inlining XML Schema. 1.4.5 XML Information Set Properties This specification refers to properties in the XML Information Set [XML Information Set]. Such properties are denoted by square brackets, e.g. [children], [attributes]. 1.4.6 WSDL 2.0 Component Model Properties This specification defines and refers to properties in the WSDL 2.0 Component Model 2. Component Model. Such properties are denoted by curly brackets, e.g. { name}, {interfaces}. This specification uses a consistent naming convention for component model properties that refer to components. If a property refers to a required or optional component, then the property name is the same as the component name. If a property refers to a set of components, then the property name is the pluralized form of the component name. 1.4.7 Z Notation Z Notation [Z Notation Reference Manual] was used in the development of this specification. Z Notation is a formal specification language that is based on standard mathematical notation. The Z Notation for this specification has been verified using the Fuzz 2000 type-checker [Fuzz 2000]. Since Z Notation is not widely known, it is not included the normative version of this specification. However, it is included in a non-normative version which allows to dynamically hide and show the Z Notation. Browsers correctly display the mathematical Unicode characters, provided that the required fonts are installed. Mathematical fonts for Mozilla Firefox can be downloaded from the Mozilla Web site. The Z Notation was used to improve the quality of the normative text that defines the Component Model, and to help ensure that the test suite covered all important rules implied by the Component Model. However, the Z Notation is non-normative, so any conflict between it and the normative text is an error in the Z Notation. Readers and implementors may nevertheless find the Z Notation useful in cases where the normative text is unclear. There are two elements of Z Notation syntax that conflict with the notational conventions described in the preceeding sections. In Z Notation, square brackets are used to introduce basic sets, e.g. [ID], which conflicts with the use of square brackets to denote XML Information Set properties 1.4.5 XML Information Set Properties. Also, in Z Notation, curly brackets are used to denote set display and set comprehension, e.g. {1, 2, 3}, which conflicts with the use of curly brackets to denote WSDL 2.0 Component Model properties 1.4.6 WSDL 2.0 Component Model Properties. However, the intended meaning of square and curly brackets should be clear from their context and this minor notational conflict should not cause any confusion. 1.4.8 BNF Pseudo-Schemas Pseudo-schemas are provided for each component, before the description of the component. They use BNF-style conventions for attributes and elements: "?" denotes optionality (i.e. zero or one occurrences), "*" denotes zero or more occurrences, "+" one or more occurrences, "[" and "]" are used to form groups, and "|" represents choice. Attributes are conventionally assigned a value which corresponds to their type, as defined in the normative schema. Elements with simple content are conventionally assigned a value which corresponds to the type of their content, as defined in the normative schema. ? + [ | ]* 2. Component Model This section describes the conceptual model of WSDL 2.0 as a set of components with attached properties, which collectively describe a Web service. This model is called the Component Model of WSDL 2.0. Components are typed collections of properties that correspond to different aspects of Web services. Each subsection herein describes a different type of component, its defined properties, and its representation as an XML Infoset [ XML Information Set]. Properties are unordered and unique with respect to the component they are associated with. Individual properties' definitions may constrain their content (e.g., to a typed value, another component, or a set of typed values or components), and components may require the presence of a property to be considered conformant. Such properties are marked as REQUIRED, whereas those that are not required to be present are marked as OPTIONAL. By convention, when specifying the mapping rules from the XML Infoset representation of a component to the component itself, an optional property that is absent in the component in question is described as being “empty”. Unless otherwise specified, when a property is identified as being a collection (a set or a list), its value may be a 0-element (empty) collection. In order to simplify the presentation of the rules that deal with sets of components, for all OPTIONAL properties whose type is a set, the absence of such a property from a component MUST be treated as semantically equivalent to the presence of a property with the same name and whose value is the empty set. In other words, every OPTIONAL set-valued property MUST be assumed to have the empty set as its default value, to be used in case the property is absent. Component definitions are serializable in XML 1.0 format but are independent of any particular serialization of the component model. Component definitions use a subset (see 2.16 XML Schema 1.0 Simple Types Used in the Component Model) of the simple types defined by the XML Schema 1.0 specification [XML Schema: Datatypes]. In addition to the direct XML Infoset representation described here, the component model allows components external to the Infoset through the mechanisms described in 4. Modularizing WSDL 2.0 descriptions. A component model can be extracted from a given XML Infoset which conforms to the XML Schema for WSDL 2.0 by recursively mapping Information Items to their identified components, starting with the wsdl:description element information item. This includes the application of the mechanisms described in 4. Modularizing WSDL 2.0 descriptions. This document does not specify a means of producing an XML Infoset representation from a component model instance. In particular, there are in general many valid ways to modularize a given component model instance into one or more XML Infosets. 2.1 Description 2.1.1 The Description Component At the abstract level, the Description component is just a container for two categories of components: WSDL 2.0 components and type system components. WSDL 2.0 components are interfaces, bindings and services. Type system components are element declarations and type definitions. Type system components describe the constraints on a message's content. By default, these constraints are expressed in terms of the [XML Information Set], i.e. they define the [local name], [namespace name], [children] and [attributes] properties of an element information item. Type systems based upon other data models are generally accommodated by extensions to WSDL 2.0; see 6. Language Extensibility. In the case where they define information equivalent to that of a XML Schema global element declaration, they can be treated as if they were such a declaration. This specification does not define the behavior of a WSDL 2.0 document that uses multiple schema languages for describing type system components simultaneously. An Element Declaration component defines the name and content model of an element information item such as that defined by an XML Schema global element declaration. It has a {name} property that is the QName of the element information item. A Type Definition component defines the content model of an element information item such as that defined by an XML Schema global type definition. It has a { name} property that is the QName of the type. Interface, Binding, Service, Element Declaration, and Type Definition components are directly contained in the Description component and are referred to as top-level components. The top-level WSDL 2.0 components contain other components, e.g. Interface Operation and Endpoint, which are referred to as nested components. Nested components may contain other nested components. The component that contains a nested component is referred to as the parent of the nested components. Nested components have a {parent} property that is a reference to their parent component. The properties of the Description component are as follows: • {interfaces} OPTIONAL. A set of Interface components. • {bindings} OPTIONAL. A set of Binding components. • {services} OPTIONAL. A set of Service components. • {element declarations} OPTIONAL. A set of Element Declaration components. • {type definitions} OPTIONAL. A set of Type Definition components. The set of top-level components contained in the Description component associated with an initial WSDL 2.0 document consists of the components defined in the initial document and the components associated with the documents that the initial document includes or imports. The component model makes no distinction between the components that are defined in the initial document versus those that are defined in the included or imported documents. However, any WSDL 2.0 document that contains component definitions that refer by QName to WSDL 2.0 components that belong to a different namespace MUST contain a ws:import element information item for that namespace (see 4.2 Importing Descriptions). Furthermore, all QName references, whether to the same or to different namespaces MUST resolve to components (see 2.19 QName resolution). In addition to WSDL 2.0 components and type system components, additional extension components MAY be added via extensibility 6. Language Extensibility. Further, additional properties to WSDL 2.0 and type system components MAY also be added via extensibility. 2.1.2 XML Representation of Description Component * [ | ]* ? [ | | ]* WSDL 2.0 definitions are represented in XML by one or more WSDL 2.0 Information Sets (Infosets), that is one or more description element information items. A WSDL 2.0 Infoset contains representations for a collection of WSDL 2.0 components which share a common target namespace. A WSDL 2.0 Infoset which contains one or more import element information items 4.2 Importing Descriptions corresponds to a collection with components drawn from multiple target namespaces. The components directly defined or included within a Description component are said to belong to the same target namespace. The target namespace therefore groups a set of related component definitions and represents an unambiguous name for the intended semantics of the collection of components. The value of the targetNamespace attribute information item SHOULD be a dereferenceable IRI (see [IETF RFC 3987]). It SHOULD resolve to a human or machine processable document that directly or indirectly defines the intended semantics of those components. It MAY resolve to a WSDL 2.0 document which provides service description information for that namespace. If a service description is split into multiple documents (which may be combined as needed via 4.1 Including Descriptions), then the targetNamespace attribute information item SHOULD resolve to a master document which includes all the WSDL 2.0 documents needed for that service description. This approach enables the WSDL 2.0 component designators' fragment identifiers to be properly resolvable. Imported components have different target namespace values from the Description component that is importing them. Thus importing is the mechanism to use components from one namespace in another set of definitions. Each WSDL 2.0 or type system component MUST be uniquely identified by its qualified name. That is, if two distinct components of the same kind (Interface , Binding, etc.) are in the same target namespace, then their QNames MUST be unique. However, different kinds of components (e.g., an Interface component and a Binding component) MAY have the same QName. Thus, QNames of components must be unique within the space of those components in a given target namespace. The description element information item has the following Infoset properties: • A [local name] of description . • A [namespace name] of "http://www.w3.org/2005/08/wsdl". • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED targetNamespace attribute information item as described below in 2.1.2.1 targetNamespace attribute information item. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information items amongst its [children], in order as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. Zero or more element information items from among the following, in any order: ☆ Zero or more include element information items (see 4.1 Including Descriptions) ☆ Zero or more import element information items (see 4.2 Importing Descriptions) ☆ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 3. An OPTIONAL types element information item (see 3. Types). 4. Zero or more element information items from among the following, in any order: ☆ interface element information items (see 2.2.2 XML Representation of Interface Component). ☆ binding element information items (see 2.9.2 XML Representation of Binding Component). ☆ service element information items (see 2.14.2 XML Representation of Service Component). ☆ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 2.1.2.1 targetNamespace attribute information item The targetNamespace attribute information item defines the namespace affiliation of top-level components defined in this description element information item. Interface, Binding and Service are top-level components. The targetNamespace attribute information item has the following Infoset properties: • A [local name] of targetNamespace • A [namespace name] which has no value The type of the targetNamespace attribute information item is xs:anyURI. Its value MUST be an absolute IRI (see [IETF RFC 3987]). 2.1.3 Mapping Description's XML Representation to Component Properties The mapping from the XML Representation of the description element information item (see 2.1.2 XML Representation of Description Component) to the properties of the Description component is described in Table 2-1.

It does this by grouping related messages into operations. An operation is a sequence of input and output messages, and an interface is a set of operations. An interface can optionally extend one or more other interfaces. To avoid circular definitions, an interface MUST NOT appear as an element of the set of interfaces it extends, either directly or indirectly. The set of operations available in an interface includes all the operations defined by the interfaces it extends, along with any operations it directly defines. The operations directly defined on an interface are referred to as the declared operations of the interface. In the process, operation components that are equivalent per 2.17 Equivalence of Components are treated as one. The interface extension mechanism behaves in a similar way for all other components that can be defined inside an interface, namely Interface Fault, Feature and Property components. Interfaces are named constructs and can be referred to by QName (see 2.19 QName resolution). For instance, Binding components refer to interfaces in this way. The properties of the Interface component are as follows: • {name} REQUIRED. An xs:QName. • {extended interfaces} OPTIONAL. A set of declared Interface components which this interface extends. • {interface faults} OPTIONAL. The set of declared Interface Fault components. The namespace name of the {name} property of each Interface Fault in this set MUST be the same as the namespace name of the {name} property of this Interface component. • {interface operations} OPTIONAL. A set of declared Interface Operation components. The namespace name of the {name} property of each Interface Operation in this set MUST be the same as the namespace name of the {name} property of this Interface component. • {features} OPTIONAL. A set of declared Feature components. • {properties} OPTIONAL. A set of declared Property components. For each Interface component in the {interfaces} property of a Description component, the {name} property MUST be unique. 2.2.2 XML Representation of Interface Component * [ | | | ]* The XML representation for an Interface component is an element information item with the following Infoset properties: • A [local name] of interface • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED name attribute information item as described below in 2.2.2.1 name attribute information item with interface [owner element]. □ An OPTIONAL extends attribute information item as described below in 2.2.2.2 extends attribute information item. □ An OPTIONAL styleDefault attribute information item as described below in 2.2.2.3 styleDefault attribute information item. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information items amongst its [children], in order, as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. Zero or more element information items from among the following, in any order: ☆ Zero or more fault element information items 2.3.2 XML Representation of Interface Fault Component. ☆ Zero or more operation element information items 2.4.2 XML Representation of Interface Operation Component. ☆ Zero or more feature element information items 2.7.2 XML Representation of Feature Component. ☆ Zero or more property element information items 2.8.2 XML Representation of Property Component. ☆ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 2.2.2.1 name attribute information item with interface [owner element] The name attribute information item together with the targetNamespace attribute information item of the [parent] description element information item forms the QName of the interface. The name attribute information item has the following Infoset properties: • A [local name] of name • A [namespace name] which has no value The type of the name attribute information item is xs:NCName. 2.2.2.2 extends attribute information item The extends attribute information item lists the interfaces that this interface derives from. The extends attribute information item has the following Infoset properties: • A [local name] of extends • A [namespace name] which has no value The type of the extends attribute information item is a list of xs:QName. 2.2.2.3 styleDefault attribute information item The styleDefault attribute information item indicates the default style (see 2.4.1.1 Operation Style) used to construct the {element declaration} properties of {interface message references} of all operations contained within the [owner element] interface . The styleDefault attribute information item has the following Infoset properties: • A [local name] of styleDefault. • A [namespace name] which has no value. The type of the styleDefault attribute information item is list of xs:anyURI. Its value, if present, MUST contain absolute IRIs (see [IETF RFC 3987]). 2.2.3 Mapping Interface's XML Representation to Component Properties The mapping from the XML Representation of the interface element information item (see 2.2.2 XML Representation of Interface Component) to the properties of the Interface component is as described in Table 2-2.

A fault is typically raised when a party is unable to communicate an error condition inside the normal message flow, or a party wishes to terminate a message exchange. A fault message may be used to communicate out of band information such as the reason for the error, the origin of the fault, as well as other informal diagnostics such as a program stack trace. An Interface Fault component describes a fault that MAY occur during invocation of an operation of the interface. The Interface Fault component declares an abstract fault by naming it and indicating the contents of the fault message. When and how the fault message flows is indicated by the Interface Operation component. The Interface Fault component provides a clear mechanism to name and describe the set of faults an interface may generate. This allows operations to easily identify the individual faults they may generate by name. This mechanism allows the ready identification of the same fault occurring across multiple operations and referenced in multiple bindings as well as reducing duplication of description for an individual fault. Note that faults other than the ones described in the Interface component can also be generated at run-time, i.e. faults are an open set. The properties of the Interface Fault component are as follows: • {name} REQUIRED. An xs:QName. • {element declaration} OPTIONAL. A reference to a Element Declaration component in the {element declarations} property of the Description component. This element represents the content or “payload” of the fault. • {features} OPTIONAL. A set of Feature components. • {properties} OPTIONAL. A set of Property components. • {parent} REQUIRED. The Interface component that contains this component in its {interface faults} property. For each Interface Fault component in the {interface faults} property of an Interface component, the {name} property must be unique. Interface Fault components are uniquely identified by the the QName of the enclosing Interface component and QName of the Interface Fault component itself. Note: Despite having a {name} property, Interface Fault components cannot be identified solely by their QName. Indeed, two Interface components whose {name} property value has the same namespace name, but different local names, can contain Interface Fault components with the same {name} property value. Thus, the {name} property of Interface Fault component is not sufficient to form the unique identity of an Interface Fault component. In cases where, due to an interface extending one or more other interfaces, two or more Interface Fault components have the same value for their {name} property, then the component models of those Interface Fault components MUST be equivalent (see 2.17 Equivalence of Components). If the Interface Fault components are equivalent then they are considered to collapse into a single component. It is an error if two Interface Fault components that are available in the same Interface component have the same value for their {name} properties but are not equivalent. Note that, due to the above rules, if two interfaces that have the same value for the namespace name of their {name} property also have one or more faults that have the same value for their {name} property then those two interfaces cannot both form part of the derivation chain of a derived interface unless those faults are the same fault. Note: For the above reason, it is considered good practice to ensure, where necessary, that the local name of the {name} property of Interface Fault components within a namespace are unique, thus allowing such derivation to occur without inadvertent error. If a type system NOT based on the XML Infoset [XML Information Set] is in use (as considered in 3.2 Using Other Schema Languages) then additional properties would need to be added to the Interface Fault component (along with extensibility attributes to its XML representation) to allow associating such message types with the message reference. 2.3.2 XML Representation of Interface Fault Component * [ | ]* The XML representation for an Interface Fault component is an element information item with the following Infoset properties: • A [local name] of fault • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED name attribute information item as described below in 2.3.2.1 name attribute information item with fault [owner element]. □ An OPTIONAL element attribute information item as described below in 2.3.2.2 element attribute information item with fault [owner element]. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information item amongst its [children], in order, as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. Zero or more element information items from among the following, in any order: ☆ Zero or more feature element information items 2.7.2 XML Representation of Feature Component ☆ Zero or more property element information items 2.8.2 XML Representation of Property Component ☆ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 2.3.2.1 name attribute information item with fault [owner element] The name attribute information item identifies a given fault element information item inside a given interface element information item. The name attribute information item has the following Infoset properties: • A [local name] of name • A [namespace name] which has no value The type of the name attribute information item is xs:NCName. 2.3.2.2 element attribute information item with fault [owner element] The element attribute information item refers, by QName, to an Element Declaration component. The element attribute information item has the following Infoset properties: • A [local name] of element . • A [namespace name] which has no value. The type of the element attribute information item is xs:QName. 2.3.3 Mapping Interface Fault's XML Representation to Component Properties The mapping from the XML Representation of the fault element information item (see 2.3.2 XML Representation of Interface Fault Component) to the properties of the Interface Fault component is as described in Table 2-3.

An operation is an interaction with the service consisting of a set of (ordinary and fault) messages exchanged between the service and the other parties involved in the interaction. The sequencing and cardinality of the messages involved in a particular interaction is governed by the message exchange pattern used by the operation (see {message exchange pattern} property). A message exchange pattern defines placeholders for messages, the participants in the pattern (i.e., the sources and sinks of the messages), and the cardinality and sequencing of messages exchanged by the participants. The message placeholders are associated with specific message types by the operation that uses the pattern by means of message and fault references (see { interface message references} and {interface fault references} properties). The service whose operation is using the pattern becomes one of the participants of the pattern. This specification does not define a machine understandable language for defining message exchange patterns, nor does it define any specific patterns. The companion specification, [WSDL 2.0 Adjuncts] defines a set of such patterns and defines identifying IRIs any of which MAY be used as the value of the {message exchange pattern} property. The properties of the Interface Operation component are as follows: • {name} REQUIRED. An xs:QName. • {message exchange pattern} REQUIRED. An xs:anyURI identifying the message exchange pattern used by the operation. This xs:anyURI MUST be an absolute IRI (see [IETF RFC 3987]). • {interface message references} OPTIONAL. A set of Interface Message Reference components for the ordinary messages the operation accepts or sends. • {interface fault references} OPTIONAL. A set of Interface Fault Reference components for the fault messages the operation accepts or sends. • {style} OPTIONAL. A set of xs:anyURIs identifying the rules that were used to construct the {element declaration} properties of {interface message references}. (See 2.4.1.1 Operation Style.) These xs:anyURIs MUST be absolute IRIs (see [IETF RFC 3986]). • {features} OPTIONAL. A set of Feature components. • {properties} OPTIONAL. A set of Property components. • {parent} REQUIRED. The Interface component that contains this component in its {interface operations} property. For each Interface Operation component in the {interface operations} property of an Interface component, the {name} property MUST be unique. Interface Operation components are uniquely identified by the the QName of the enclosing Interface component and QName of the Interface Operation component itself. Note: Despite having a {name} property, Interface Operation components cannot be identified solely by their QName. Indeed, two Interface components whose {name} property value has the same namespace name, but different local names, can contain Interface Operation components with the same {name} property value. Thus, the {name} property of Interface Operation components is not sufficient to form the unique identity of an Interface Operation component. In cases where, due to an interface extending one or more other interfaces, two or more Interface Operation components have the same value for their {name} property, then the component models of those Interface Operation components MUST be equivalent (see 2.17 Equivalence of Components). If the Interface Operation components are equivalent then they are considered to collapse into a single component. It is an error if two Interface Operation components have the same value for their {name} property but are not equivalent. Note that, due to the above rules, if two interfaces that have the same value for the namespace name of their {name} property also have one or more operations that have the same value for their {name} property then those two interfaces cannot both form part of the derivation chain of a derived interface unless those operations are the same operation. Note: For the above reason, it is considered good practice to ensure, where necessary, that the {name} property of Interface Operation components within a namespace are unique, thus allowing such derivation to occur without inadvertent error. More than one Interface Fault Reference component in the {interface fault references} property of an Interface Operation component may refer to the same message label. In that case, the listed fault types define alternative fault messages. This allows one to indicate that there is more than one type of fault that is related to that message. 2.4.1.1 Operation Style If the {style} property of an Interface Operation component has a value then that value (a set of IRIs) implies the rules that were used to define the { element declaration} properties (or other property which defines the content of the message properties; see 3.2 Using Other Schema Languages) of all the Interface Message Reference components which are members of the {interface message references} property of that component. Although a given operation style has the ability to constrain all input and output messages for an operation, it MAY choose to contrain only the former or the latter or any combination thereof. Note that the property MAY not have any value. If this property has a value (a set of IRIs), then for each individual IRI that is an element of that set, the rules implied by that IRI (such as rules that govern the schemas) MUST be followed or it is an error. So, if the set of IRIs has more than one item in it, then the rules implied by ALL the IRIs must be adhered to by the content definitions. The WSDL Version 2.0 Part 2: Adjuncts specification [WSDL 2.0 Adjuncts] defines the following operation style: • RPC Style 2.4.2 XML Representation of Interface Operation Component * [ | | [ | | | ]+ ]* The XML representation for an Interface Operation component is an element information item with the following Infoset properties: • A [local name] of operation • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • Two or more attribute information items amongst its [attributes] as follows: □ A REQUIRED name attribute information item as described below in 2.4.2.1 name attribute information item with operation [owner element]. □ A REQUIRED pattern attribute information item as described below in 2.4.2.2 pattern attribute information item with operation [owner element]. □ An OPTIONAL style attribute information item as described below in 2.4.2.3 style attribute information item with operation [owner element] . □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • One or more element information item amongst its [children], in order, as follows: 1.

The name attribute information item has the following Infoset properties: • A [local name] of name • A [namespace name] which has no value The type of the name attribute information item is xs:NCName. 2.4.2.2 pattern attribute information item with operation [owner element] The pattern attribute information item identifies the message exchange pattern a given operation uses. The pattern attribute information item has the following Infoset properties: • A [local name] of pattern • A [namespace name] which has no value The type of the pattern attribute information item is xs:anyURI. Its value MUST be an absolute IRI (see [IETF RFC 3987]). 2.4.2.3 style attribute information item with operation [owner element] The style attribute information item indicates the rules that were used to construct the {element declaration} properties of the Interface Message Reference components which are members of the {interface message references} property of the [owner element] operation.

By default, the element is defined in the XML Infoset [XML Information Set]. A message exchange pattern defines a set of placeholder messages that participate in the pattern and assigns them unique message labels within the pattern (e.g. 'In', 'Out'). The purpose of an Interface Message Reference component is to associate an actual message element (XML element declaration or some other declaration (see 3.2 Using Other Schema Languages)) with a message in the pattern, as identified by its message label. Later, when the message exchange pattern is instantiated, messages corresponding to that particular label will follow the element assignment made by the Interface Message Reference component. The properties of the Interface Message Reference component are as follows: • {message label} REQUIRED. An xs:NCName. This property identifies the role this message plays in the {message exchange pattern} of the Interface Operation component this message is contained within. The value of this property MUST match the name of a placeholder message defined by the message exchange pattern. • {direction} REQUIRED. An xs:token with one of the values in or out, indicating whether the message is coming to the service or going from the service, respectively. The direction MUST be the same as the direction of the message identified by the {message label} property in the {message exchange pattern} of the Interface Operation component this is contained within. • {message content model} REQUIRED. An xs:token with one of the values #any, #none, #other, or #element. A value of #any indicates that the message content is any single element. A value of #none indicates there is no message content. A value of #other indicates that the message content is described by some other extension property that references a declaration in a non-XML extension type system. A value of #element indicates that the message consists of a single element described by the global element declaration referenced by the {element declaration} property. This property is used only when the message is described using an XML based data model. • {element declaration} OPTIONAL. A reference to an XML element declaration in the {element declarations} property of the Description component. This element represents the content or “payload” of the message. When the { message content model} property has the value #any or #none the {element declaration} property MUST be empty. • {features} OPTIONAL. A set of Feature components. • {properties} OPTIONAL. A set of Property components. • {parent} REQUIRED. The Interface Operation component that contains this component in its {interface message references} property. For each Interface Message Reference component in the {interface message references} property of an Interface Operation component, its {message label} property MUST be unique. If a type system not based upon the XML Infoset is in use (as considered in 3.2 Using Other Schema Languages) then additional properties would need to be added to the Interface Message Reference component (along with extensibility attributes to its XML representation) to allow associating such message types with the message reference. 2.5.2 XML Representation of Interface Message Reference Component * [ | ]* * [ | ]* The XML representation for an Interface Message Reference component is an element information item with the following Infoset properties: • A [local name] of input or output • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • Zero or more attribute information items amongst its [attributes] as follows: □ An OPTIONAL messageLabel attribute information item as described below in 2.5.2.1 messageLabel attribute information item with input or output [owner element]. If the {message exchange pattern} of the Interface Operation component has only one message in a given direction, then the messageLabel attribute information item is optional for the XML representation of the Interface Message Reference component with that {direction}. □ An OPTIONAL element attribute information item as described below in 2.5.2.2 element attribute information item with input or output [owner element]. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information item amongst its [children], in order, as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2.

The messageLabel attribute information item has the following Infoset properties: • A [local name] of messageLabel • A [namespace name] which has no value The type of the messageLabel attribute information item is xs:NCName. 2.5.2.2 element attribute information item with input or output [owner element] The element attribute information item has the following Infoset properties: • A [local name] of element . • A [namespace name] which has no value. The type of the element attribute information item is a union of xs:QName and xs:token where the allowed token values are #any, #none, or #other. 2.5.3 Mapping Interface Message Reference's XML Representation to Component Properties The mapping from the XML Representation of the message reference element information item (see 2.5.2 XML Representation of Interface Message Reference Component) to the properties of the Interface Message Reference component (see 2.5.1 The Interface Message Reference Component) is as described in Table 2-5.

A message exchange pattern defines a set of placeholder messages that participate in the pattern and assigns them unique message labels within the pattern (e.g. 'In', 'Out'). The purpose of an Interface Fault Reference component is to associate an actual message type (XML element declaration or some other declaration (see 3.2 Using Other Schema Languages) for message content, as specified by an Interface Fault component) with a fault message occurring in the pattern. In order to identify the fault message it describes, the Fault Reference component uses the message label of the message the fault is associated with as a key. The companion specification [WSDL 2.0 Adjuncts] defines two fault patterns that a given message exchange pattern may use. For the pattern fault-replaces-message, the message that the fault relates to identifies the message in place of which the declared fault message will occur. Thus, the fault message will travel in the same direction as the message it replaces in the pattern. For the pattern message-triggers-fault, the message that the fault relates to identifies the message after which the indicated fault may occur, in the opposite direction of the referred to message. That is, the fault message will travel in the opposite direction of the message it comes after in the pattern. The properties of the Interface Fault Reference component are as follows: • {interface fault} REQUIRED. An Interface Fault component in the {interface faults} property of the [parent] Interface Operation component's [parent] Interface component, or an Interface component that it directly or indirectly extends. Identifying the Interface Fault component therefore indirectly defines the actual content or payload of the fault message. • {message label} REQUIRED. An xs:NCName. This property identifies the message this fault relates to among those defined in the {message exchange pattern} property of the Interface Operation component it is contained within. The value of this property MUST match the name of a placeholder message defined by the message exchange pattern. • {direction} REQUIRED. A xs:token with one of the values in or out, indicating whether the fault is coming to the service or going from the service, respectively. The direction MUST be consistent with the direction implied by the fault rule used in the message exchange pattern of the operation. For example, if the fault rule fault-replaces-message is used, then a fault which refers to an outgoing message would have a {direction} property value of out. On the other hand, if the fault rule message-triggers-fault is used, then a fault which refers to an outgoing message would have a {direction} property value of in as the fault travels in the opposite direction of the message. • {features} OPTIONAL. A set of Feature components. • {properties} OPTIONAL. A set of Property components. • {parent} REQUIRED. The Interface Operation component that contains this component in its {interface fault references} property. For each Interface Fault Reference component in the {interface fault references } property of an Interface Operation component, the combination of its { interface fault} and {message label} properties MUST be unique. 2.6.2 XML Representation of Interface Fault Reference * [ | ]* * * [ | ]* * The XML representation for a Interface Fault Reference component is an element information item with the following Infoset properties: • A [local name] of infault or outfault • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED ref attribute information item as described below in 2.6.2.1 ref attribute information item with infault, or outfault [owner element]. □ An OPTIONAL messageLabel attribute information item as described below in 2.6.2.2 messageLabel attribute information item with infault, or outfault [owner element]. If the {message exchange pattern} of the Interface Operation component has only one message with a given direction, the messageLabel attribute information item is optional for the XML representation of any Interface Fault Reference component with the same value for {direction} (if the fault pattern of the {message exchange pattern} is fault-replaces-message) or of any Interface Fault Reference component with the opposite value for {direction} (if the fault pattern is message-triggers-fault). □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information item amongst its [children], in order, as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. Zero or more element information items from among the following, in any order: ☆ Zero or more feature element information items 2.7.2 XML Representation of Feature Component ☆ Zero or more property element information items 2.8.2 XML Representation of Property Component ☆ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 2.6.2.1 ref attribute information item with infault , or outfault [owner element] The ref attribute information item refers to a fault component. The ref attribute information item has the following Infoset properties: • A [local name] of ref • A [namespace name] which has no value The type of the ref attribute information item is xs:QName. 2.6.2.2 messageLabel attribute information item with infault , or outfault [owner element] The messageLabel attribute information item identifies the message in the message exchange pattern of the given operation element information item to which this fault is related to. The messageLabel attribute information item has the following Infoset properties: • A [local name] of messageLabel • A [namespace name] which has no value The type of the messageLabel attribute information item is xs:NCName. 2.6.3 Mapping Interface Fault Reference's XML Representation to Component Properties The mapping from the XML Representation of the message reference element information item (see 2.6.2 XML Representation of Interface Fault Reference) to the properties of the Interface Fault Reference component (see 2.6.1 The Interface Fault Reference Component) is as described in Table 2-6.

Although WSDL 2.0 imposes no constraints on the potential scope of such features, examples might include “reliability”, “security”, “correlation”, and “routing”. The presence of a Feature component in a WSDL 2.0 description indicates that the service supports the feature and may require that a client that interacts with the service use that feature. Each Feature is identified by its IRI. Note that the WSDL 2.0's feature concept is derived from SOAP 1.2's abstract feature concept ([SOAP 1.2 Part 1: Messaging Framework]). Thus, by definition, every SOAP 1.2 abstract feature is also a WSDL 2.0 feature. Hence, there is no need to define a separate WSDL 2.0 feature in order to use a particular SOAP 1.2 feature. The SOAP 1.2 feature can be used directly. The properties of the Feature component are as follows: • {ref} REQUIRED. An xs:anyURI. This xs:anyURI MUST be an absolute IRI as defined by [IETF RFC 3987]. This IRI SHOULD be dereferenceable to a document that directly or indirectly defines the meaning and use of the Feature that it identifies. • {required} REQUIRED. An xs:boolean. If the value of this property is true, then the client MUST use the Feature that is identified by the {ref} IRI. Otherwise, the client MAY use the Feature that is identified by the {ref} IRI. In either case, if the client does use the Feature that is identified by the {ref} IRI, then the client MUST obey all semantics implied by the definition of that Feature. • {parent} REQUIRED. The component that contains this component in its { features} property. The {ref} property of a Feature component MUST be unique within the {features} property of an Interface, Interface Fault, Interface Operation, Interface Message Reference, Interface Fault Reference, Binding, Binding Fault, Binding Operation, Binding Message Reference, Binding Fault Reference, Service, or Endpoint component. 2.7.1.1 Feature Composition Model The set of features which are required or available for a given component consists of the combined set of ALL feature declarations applicable to that component. A feature is applicable to a component if: • it is asserted directly within that component, or • it is asserted in a containing component, or • it is asserted in a component referred to by the current component. Many of the component types in the component model contain a {features} property, which is a set of Feature components. We refer to these as the declared features of the component. Furthermore, the {features} property is itself a subset of Feature components that are required or available for the given component as determined by the Feature Composition Model. We refer to these as the in-scope features of the component. Following these rules, the set of features applicable at each component are as follows: • Interface component: all features asserted within the Interface component and those with any extended Interface components. • Interface Fault component: all features asserted within the Interface Fault component and those within the parent Interface component. • Interface Operation component: all features asserted within the Interface Operation component and those within the parent Interface component. • Interface Message Reference component: all features asserted within the Interface Message Reference component, those within the parent Interface Operation component and those within its parent Interface component. • Interface Fault Reference component: all features asserted within the Interface Fault Reference component, those within the parent Interface Operation component and those within its parent Interface component. • Binding component: all features asserted within the Binding component and those within the Interface component referred to by the Binding component (if any). • Binding Fault component: all features asserted within the Binding Fault component, those within the parent Binding component, those within the corresponding Interface Fault component, and those within the Interface component referred to by the Binding component. • Binding Operation component: all features asserted within the Binding Operation component, those within the parent Binding component, those within the corresponding Interface Operation component, and those within the Interface component referred to by the Binding component. • Binding Message Reference component: all features asserted within the Binding Message Reference component, those within the parent Binding operation component, those within its parent Binding component, those within the corresponding Interface Message Reference component, and those within the Interface component referred to by the Binding component. • Binding Fault Reference component: all features asserted within the Binding Fault Reference component, those within the parent Binding Operation component, those within its parent Binding component, those within the corresponding Interface Fault Reference component, and those within the Interface component referred to by the Binding component. • Service component: all features asserted within the Service component and those within the Interface implemented by the Service component. • Endpoint component: all features asserted within the Endpoint component, whose within the Binding component implemented by the Endpoint component, and those within the parent Service component. If a given feature is asserted at multiple locations, then the value of that feature at a particular component is determined by the conjunction of all the constraints implied by its asserted values. If a feature is not required then it may or may not be engaged, but if a feature is required then it must be engaged. Therefore, the conjunction of a required value and a non-required value is a required value. A composed feature is required if and only if at least one of its asserted values is required. This rule may be summarized as "true trumps". 2.7.1.1.1 Example of Feature Composition Model In the following example, the depositFunds operation on the BankService has to be used with the ISO9001 , the notarization and the secure-channel features; they are all in scope. The fact that the notarization feature is declared both in the operation and in the binding has no effect. ... ... ... 2.7.2 XML Representation of Feature Component * The XML representation for a Feature component is an element information item with the following Infoset properties: • A [local name] of feature • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED ref attribute information item as described below in 2.7.2.1 ref attribute information item with feature [owner element]. □ An OPTIONAL required attribute information item as described below in 2.7.2.2 required attribute information item with feature [owner element]. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information items amongst its [children], in order as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 2.7.2.1 ref attribute information item with feature [owner element] The ref attribute information item specifies the IRI of the feature. The ref attribute information item has the following Infoset properties: • A [local name] of ref • A [namespace name] which has no value The type of the ref attribute information item is xs:anyURI . 2.7.2.2 required attribute information item with feature [owner element] The required attribute information item specifies whether the use of the feature is mandatory or optional. The required attribute information item has the following Infoset properties: • A [local name] of required • A [namespace name] which has no value The type of the required attribute information item is xs:boolean . 2.7.3 Mapping Feature's XML Representation to Component Properties The mapping from the XML Representation of the feature element information item (see 2.7.2 XML Representation of Feature Component) to the properties of the Feature component (see 2.7.1 The Feature Component) is as described in Table 2-7. Table 2-7. Mapping from XML Representation to Feature Component Properties ┌──────────┬──────────────────────────────────────────────────────────────────┐ │ Property │ Value │ ├──────────┼──────────────────────────────────────────────────────────────────┤ │{ref} │The actual value of the ref attribute information item. │ ├──────────┼──────────────────────────────────────────────────────────────────┤ │{required}│The actual value of the required attribute information item, if │ │ │present, otherwise "false". │ ├──────────┼──────────────────────────────────────────────────────────────────┤ │{parent} │The component corresponding to the element information item in │ │ │[parent]. │ └──────────┴──────────────────────────────────────────────────────────────────┘ 2.8 Property 2.8.1 The Property Component A “property” in the Features and Properties architecture represents a named runtime value which affects the behavior of some aspect of a Web service interaction, much like an environment variable. For example, a reliable messaging SOAP module may specify a property to control the number of retries in the case of network failure. WSDL 2.0 documents may specify the value constraints for these properties by referring to a Schema type, or by specifying a particular value. Properties, and hence property values, can be shared amongst features/bindings/modules, and are named with IRIs precisely to allow this type of sharing. The properties of the Property component are as follows: • {ref} REQUIRED. An xs:anyURI. This xs:anyURI MUST an absolute IRI as defined by [IETF RFC 3987]. This IRI SHOULD be dereferenceable to a document that directly or indirectly defines the meaning and use of the Property that it identifies. • {value constraint} OPTIONAL. A reference to a Type Definition component in the {type definitions} property of the Description component constraining the value of the Property, or the token #value if the {value} property is not empty. • {value} OPTIONAL. The value of the Property, an ordered list of child information items, as specified by the [children] property of element information items in [XML Information Set]. • {parent} REQUIRED. The component that contains this component in its { properties} property. The {ref} property of a Property component MUST be unique within the { properties} property of an Interface, Interface Fault, Interface Operation, Interface Message Reference, Interface Fault Reference, Binding, Binding Fault, Binding Operation, Binding Message Reference, Binding Fault Reference, Service, or Endpoint component. If a type system not based upon the XML Infoset is in use (as considered in 3.2 Using Other Schema Languages) then additional properties would need to be added to the Property component (along with extensibility attributes to its XML representation) to allow using such a type system to describe values and constraints for properties. 2.8.1.1 Property Composition Model At runtime, the behavior of features, (SOAP) modules and bindings may be affected by the values of in-scope properties. Properties combine into a virtual “execution context” which maps property names (IRIs) to constraints. Each property IRI MAY therefore be associated with AT MOST one property constraint for a given interaction. The set of properties which are required or available for a given component consists of the combined set of ALL property declarations applicable to that component. A property is applicable to a component if: • it is asserted directly within that component, or • it is asserted in a containing component, or • it is asserted in a component referred to by the current component. Many of the component types in the component model contain a {properties} property, which is a set of Property components. We refer to these as the declared properties of the component. Furthermore, the {properties} property is itself a subset of Property components that are required or available for the given component as determined by the Property Composition Model. We refer to these as the in-scope properties of the component. Following these rules, the set of properties applicable at each component are as follows: • Interface component: all properties asserted within the Interface component and those with any extended Interface components. • Interface Fault component: all properties asserted within the Interface Fault component and those within the parent Interface component. • Interface Operation component: all properties asserted within the Interface Operation component and those within the parent Interface component. • Interface Message Reference component: all properties asserted within the Interface Message Reference component, those within the parent Interface Operation component and those within its parent Interface component. • Binding component: all properties asserted within the Binding component and those within the Interface component referred to by the Binding component (if any). • Binding Fault component: all properties asserted within the Binding Fault component, those within the parent Binding component, those within the corresponding Interface Fault component, and those within the Interface component referred to by the Binding component. • Binding Operation component: all properties asserted within the Binding Operation component, those within the parent Binding component, those within the corresponding Interface Operation component, and those within the Interface component referred to by the Binding component. • Binding Message Reference component: all properties asserted within the Binding Message Reference component, those within the parent Binding Operation component, those within its parent Binding component, those within the corresponding Interface Message Reference component, and those within the Interface component referred to by the Binding component. • Binding Fault Reference component: all properties asserted within the Binding Fault Reference component, those within the parent Binding Operation component, those within its parent Binding component, those within the corresponding Interface Fault Reference component, and those within the Interface component referred to by the Binding component. • Service component: all properties asserted within the Service component and those within the Interface implemented by the Service component. • Endpoint component: all properties asserted within the Endpoint component, whose within the Binding component implemented by the Endpoint component, and those within the parent Service component. Note that, in the text above, “property constraint” (or, simply, “constraint”) is used to mean EITHER a constraint inside a Property component OR a value , since value may be considered a special case of constraint . If a given Property is asserted at multiple locations, then the value of that Property at a particular component is determined by the conjunction of all the constraints of its in-scope Property components. A Property constraint asserts that, for a given interaction, the value of a Property is either a specified value or belongs to a specified set of values. A specified value may be regarded as a singleton set, so in both cases a Property constraint corresponds to an assertion that the Property value belongs to some set. The conjunction of all the constraints associated with the in-scope properties is an assertion that the property value belongs to each of the associated sets, or equivalently, that the value belongs to the intersection of all the associated sets. If the intersection of the associated sets is empty, then the property constraints are mutually incompatible, and the composition is invalid. Therefore, the intersection of the associated sets SHOULD NOT be empty. Note: The reason that we phrase the requirement for a non-empty intersection as SHOULD rather than MUST, is that in general, it may be computationally difficult to determine by inspection of the type definitions that the intersection of two or more value sets is empty. Therefore, it is not a strict validity requirement that the intersection of the value sets be non-empty. An empty intersection will always result in failure of the service at run-time. However, it is in general feasible to test specified values for either equality or membership in value sets. All specified values MUST be equal and belong to each specified value set. 2.8.2 XML Representation of Property Component * [ | ]? The XML representation for a Property component is an element information item with the following Infoset properties: • A [local name] of property • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED ref attribute information item as described below in 2.8.2.1 ref attribute information item with property [owner element]. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information items amongst its [children], in order as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. One OPTIONAL element information item from among the following: ☆ A value element information item as described in 2.8.2.2 value element information item with property [parent] ☆ A constraint element information item as described in 2.8.2.3 constraint element information item with property [parent] 3. Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 2.8.2.1 ref attribute information item with property [owner element] The ref attribute information item specifies the IRI of the property. It has the following Infoset properties: • A [local name] of ref • A [namespace name] which has no value The type of the ref attribute information item is xs:anyURI . 2.8.2.2 value element information item with property [parent] xs:anyType The value element information item specifies the value of the property. It has the following Infoset properties: • A [local name] of value • A [namespace name] of "http://www.w3.org/2005/08/wsdl" The type of the value element information item is xs:anyType . 2.8.2.3 constraint element information item with property [parent] xs:QName The constraint element information item specifies a constraint on the value of the property. It has the following Infoset properties: • A [local name] of constraint • A [namespace name] of "http://www.w3.org/2005/08/wsdl" The type of the constraint attribute information item is xs:QName . 2.8.3 Mapping Property's XML Representation to Component Properties The mapping from the XML Representation of the property element information item (see 2.8.2 XML Representation of Property Component) to the properties of the Property component (see 2.8.1 The Property Component) is as described in Table 2-8.

That is, a Binding component defines the implementation details necessary to access the service. Binding components can be used to describe such information in a reusable manner for any interface or specifically for a given interface. Furthermore, binding information MAY be specified on a per-operation basis (see 2.11.1 The Binding Operation Component) within an interface in addition to across all operations of an interface. If a Binding component specifies any operation-specific binding details (by including Binding Operation components) or any fault binding details (by including Binding Fault components) then it MUST specify an interface the Binding component applies to, so as to indicate which interface the operations come from. Conversely, a Binding component which omits any operation-specific binding details and any fault binding details MAY omit specifying an interface. Binding components that do not specify an interface MAY be used to specify operation-independent binding details for Service components with different interfaces. That is, such Binding components are reusable across one or more interfaces. No concrete binding details are given in this specification. The companion specification, WSDL (Version 2.0): Adjuncts [WSDL 2.0 Adjuncts] defines such bindings for SOAP 1.2 [SOAP 1.2 Part 1: Messaging Framework] and HTTP [IETF RFC 2616]. Other specifications MAY define additional binding details. Such specifications are expected to annotate the Binding component (and its sub-components) with additional properties and specify the mapping from the XML representation to those properties. A Binding component that defines bindings for an Interface component MUST define bindings for all the operations of that Interface component. The bindings may occur via defaulting rules which allow one to specify default bindings for all operations (see, for example [WSDL 2.0 Adjuncts]) or by directly listing each Interface Operation component of the Interface component and defining bindings for them. Thus, it is an error for a Binding component to not define bindings for all the Interface Operation components of the Interface component for which the Binding\ component purportedly defines bindings for. Bindings are named constructs and can be referred to by QName (see 2.19 QName resolution). For instance, Endpoint components refer to bindings in this way. The properties of the Binding component are as follows: • {name} REQUIRED. An xs:QName. • {interface} OPTIONAL. An Interface component indicating the interface for which binding information is being specified. • {type} REQUIRED. An xs:anyURI. This xs:anyURI MUST be an absolute IRI as defined by [IETF RFC 3987]. The value of this IRI indicates what kind of concrete binding details are contained within this Binding component. Specifications (such as [WSDL 2.0 Adjuncts] ) that define such concrete binding details MUST specify appropriate values for this property. The value of this property MAY be the namespace name of the extension elements or attributes which define those concrete binding details. • {binding faults} OPTIONAL. A set of Binding Fault components. • {binding operations} OPTIONAL. A set of Binding Operation components. • {features} OPTIONAL. A set of Feature components. • {properties} OPTIONAL. A set of Property components. For each Binding component in the {bindings} property of a Description component, the {name} property MUST be unique. 2.9.2 XML Representation of Binding Component * [ | | | ]* The XML representation for a Binding component is an element information item with the following Infoset properties: • A [local name] of binding • A [namespace name] of "http://www.w3.org/2005/08/wsdl" • Two or more attribute information items amongst its [attributes] as follows: □ A REQUIRED name attribute information item as described below in 2.9.2.1 name attribute information item with binding [owner element]. □ An OPTIONAL interface attribute information item as described below in 2.9.2.2 interface attribute information item with binding [owner element]. □ An REQUIRED type attribute information item as described below in 2.9.2.3 type attribute information item with binding [owner element]. □ Zero or more namespace qualified attribute information items whgse [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information items amongst its [children], in order, as follows: 1. Zero or more documentation element information items (see 5. Documentation). 2. Zero or more element information items from among the following, in any order: ☆ Zero or more fault element information items (see 2.10.2 XML Representation of Binding Fault Component). ☆ Zero or more operation element information items (see 2.11.2 XML Representation of Binding Operation Component). ☆ Zero or more feature element information items (see 2.7.2 XML Representation of Feature Component). ☆ Zero or more property element information items (see 2.8.2 XML Representation of Property Component). ☆ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". Such element information items are considered to be binding extension elements(see 2.9.2.4 Binding extension elements). 2.9.2.1 name attribute information item with binding [owner element] The name attribute information item together with the targetNamespace attribute information item of the description element information item forms the QName of the binding.

A particular fault of an interface is uniquely identified by its {name} property. Note that the fault does not occur by itself - it occurs as part of a message exchange as defined by an Interface Operation component (and its binding counterpart the Binding Operation component). Thus, the fault binding information specified in a Binding Fault component describes how faults that occur within a message exchange of an operation will be formatted and carried in the transport. The properties of the Binding Fault component are as follows: • {interface fault} REQUIRED. An Interface Fault component in the {interface faults} property of the Interface component identified by the {interface} property of the parent Binding component, or an Interface component that that Interface component directly or indirectly extends. This is the Interface Fault component for which binding information is being specified. • {features} OPTIONAL. A set of Feature components. • {properties} OPTIONAL. A set of Property components. • {parent} REQUIRED. The Binding component that contains this component in its {binding faults} property. For each Binding Fault component in the {binding faults} property of a Binding component, the {interface fault} property MUST be unique.

For instance, two string values are equivalent if they contain the same sequence of Unicode characters, as described in [Character Model for the WWW] • Values which are references to other components are considered equivalent when they refer to equivalent components (as determined above). • List-based values are considered equivalent if they have the same length and their elements at corresponding positions are equivalent. • Finally, set-based values are considered equivalent if they contain corresponding equivalent values, without regard to order. Extension properties which are not string values, sets of strings or references MUST describe their values' equivalence rules. Because different top-level components (e.g., Interface, Binding, and Service) are required to have different names, it is possible to determine whether two top-level components of a given type are equivalent by examining their {name} property. 2.18 Symbol Spaces This specification defines three symbol spaces, one for each top-level component type (Interface, Binding and Service). Within a symbol space, all qualified names (that is, the {name} property) are unique. Between symbol spaces, the names need not be unique. Thus it is perfectly coherent to have, for example, a binding and an interface that have the same name. When XML Schema is being used as one of the type systems for a WSDL 2.0 description, then six other symbol spaces also exist, one for each of: global element declarations, global attribute declarations, named model groups, named attribute groups, type definitions and key constraints, as defined by [XML Schema: Structures]. Other type systems may define additional symbol spaces. 2.19 QName resolution In its serialized form WSDL 2.0 makes significant use of references between components. Such references are made using the Qualified Name, or QName, of the component being referred to. QNames are a tuple, consisting of two parts; a namespace name and a local name. The namespace name for a component is represented by the value of the targetNamespace attribute information item of the [parent] description element information item and the local name is represented by the {name} property of the component. QName references are resolved by looking in the appropriate property of the Description component. For example, to resolve a QName of an interface (as referred to by the interface attribute information item on a binding), the { interfaces} property of the Description component would be inspected. If the appropriate property of the Description component does not contain a component with the required QName then the reference is a broken reference. It is an error for a Description component to have such broken references. 2.20 Comparing URIs and IRIs This specification uses absolute URIs and IRIs to identify several components (for example, features and properties) and components characteristics (for example, operation message exchange patterns and styles). When such absolute URIs and IRIs are being compared to determine equivalence (see 2.17 Equivalence of Components) they MUST be compared character-by-character as indicated in [ TAG URI FINDING]. 3. Types * [ | | other extension elements ]* The content of messages and faults may be constrained using type system components. These constraints are based upon a specific data model, and expressed using a particular schema language. Although a variety of data models can be accommodated (through WSDL 2.0 extensions), this specification only defines a means of expressing constraints based upon the XML Infoset [XML Information Set]. Furthermore, although a number of alternate schema languages can be used to constrain the XML Infoset (as long as they support the semantics of either inlining or importing schema), this specification only defines the use of XML Schema [XML Schema: Structures], [XML Schema: Datatypes]. Specifically, the {element declarations} and {type definitions} properties of the Description component are collections of imported and inlined schema components that describe Infoset element information items. When extensions are used to enable the use of a non-Infoset data model, or a non-Schema constraint language, the wsdl:required attribute information item MAY be used to require support for that extension. Note: Support for the W3C XML Schema [XML Schema: Structures], [XML Schema: Datatypes ] is included in the conformance criteria for WSDL 2.0 documents (see 3.1 Using W3C XML Schema Description Language ). The schema components contained in the {element declarations} property of the Description component provide the type system used for Interface Message Reference and Interface Fault components. Interface Message Reference components indicate their structure and content by using the standard attribute information items element , or for alternate schema languages in which these concepts do not map well, by using alternative attribute information item extensions. Interface Fault components behave similarly. Such extensions should define how they reference type system components. Such type system components MAY appear in additional collection properties on the Description component. The schema components contained in the {type definitions} property of the Description component provide the type system used for constraining the values of properties described by Property components. Extensions in the form of attribute information items can be used to refer to constraints (type definitions or analogous constructs) described using other schema languages or type systems. Such components MAY appear in additional collection properties on the Description component. The types element information item encloses data type definitions, based upon the XML Infoset, used to define messages and has the following Infoset properties: • A [local name] of types . • A [namespace name] of "http://www.w3.org/2005/08/wsdl". • Zero or more namespace qualified attribute information items whose [namespace name] is NOT http://www.w3.org/2005/08/wsdl • Zero or more element information items amongst its [children] as follows: □ Zero or more documentation element information items (see 5. Documentation) in its [children] property. □ Zero or more element information items from among the following, in any order: ☆ xs:import element information items ☆ xs:schema element information items ☆ Other namespace qualified element information items whose namespace is NOT http://www.w3.org/2005/08/wsdl 3.1 Using W3C XML Schema Description Language XML Schema MAY be used as the schema language via import or inlining. A WSDL 2.0 description MUST NOT refer to XML Schema components in a given namespace unless an xs:import or xs:schema statement for that namespace is present. That is, using the xs:import or xs:schema constructs is a necessary condition for making XML Schema components available to a WSDL 2.0 description.

The schema components defined in the imported namespace are available for reference by QName (see 2.19 QName resolution). Note that only components in the imported namespace are available for reference in the WSDL 2.0 document. A child element information item of the types element information item is defined with the Infoset properties as follows: • A [local name] of "import". • A [namespace name] of "http://www.w3.org/2001/XMLSchema". • One or two attribute information items as follows: □ A REQUIRED namespace attribute information item as described below. □ An OPTIONAL schemaLocation attribute information item as described below. 3.1.1.1 namespace attribute information item The namespace attribute information item defines the namespace of the element declarations and type definitions imported from the referenced schema. The referenced schema MUST contain a targetNamespace attribute information item on its xs:schema element information item and the values of these two attribute information items MUST be identical. It is an error to import a schema that does not have a targetNamespace attribute information item on its xs:schema element information item. Such schemas must first be included (using xs:include ) in a schema that contains a targetNamespace attribute information item on its xs:schema element information item, which can then be either imported or inlined in the WSDL 2.0 document. The namespace attribute information item has the following Infoset properties: • A [local name] of namespace • A [namespace name] which has no value. The type of the namespace attribute information item is xs:anyURI. 3.1.1.2 schemaLocation attribute information item The schemaLocation attribute information item, if present, provides a hint to the XML Schema processor as to where the schema may be located. Caching and cataloging technologies may provide better information than this hint. The schemaLocation attribute information item has the following Infoset properties: • A [local name] of schemaLocation. • A [namespace name] which has no value. The type of the schemaLocation attribute information item is xs:anyURI. It is an error if a QName is not resolved (see 2.19 QName resolution). When resolving QNames references for schema definitions, the namespace MUST be imported by the referring WSDL 2.0 document. If the namespace so referenced is contained in an inline schema, it MAY be imported without a schemaLocation attribute, so long as the inline schema has been resolved in the current component model. 3.1.2 Inlining XML Schema Inlining an XML schema uses the existing top-level xs:schema element information item defined by XML Schema [XML Schema: Structures]. It may be viewed as simply cutting and pasting an existing schema document to a location inside the types element information item. The schema components defined and declared in the inlined schema document are available to WSDL 2.0 for reference by QName (see 2.19 QName resolution). Note that only components defined and declared in the schema itself and components included by it via xs:include are available to WSDL 2.0. Specifically components that the schema imports via xs:import are NOT available to WSDL 2.0. Similarly, components defined in an inlined XML schema are NOT automatically made available to a WSDL 2.0 description that imported (using wsdl:import ) the description that inlines the schema (see 4.2 Importing Descriptions for more details). For this reason, it is recommended that XML schema documents intended to be shared across several WSDL 2.0 descriptions be placed in separate documents and imported using xs:import , rather than inlined inside a WSDL 2.0 document. Inside an inlined XML schema, the xs:import and xs:include element information items MAY be used to refer to other XML schemas inlined in the same or other WSDL 2.0 document, provided that an appropriate value, such as a fragment identifier (see [XML Schema: Structures] 4.3.1) is specified for their schemaLocation attribute information items. For xs:import , the schemaLocation attribute is not required so long as the namespace has been resolved in the current component model. The semantics of such element information items are governed solely by the XML Schema specification [XML Schema: Structures]. Note: It is NOT an error to inline two or more schemas from the same targetNamespace . For example, two or more inlined schemas may have the same targetNamespace provided that they do not define the same elements or types. It is the responsibility of the underlying XML Schema processor to sort out a coherent set of schema components. The xs:schema element information item has the following Infoset properties: • A [local name] of schema. • A [namespace name] of "http://www.w3.org/2001/XMLSchema". • A REQUIRED targetNamespace attribute information item, amongst its [attributes] as described below. • Additional OPTIONAL attribute information items as specified for the xs:schema element information item by the XML Schema specification. • Zero or more child element information items as specified for the xs:schema element information item by the XML Schema specification. 3.1.2.1 targetNamespace attribute information item The targetNamespace attribute information item defines the namespace of the element declarations and type definitions inlined in its [owner element] xs:schema element information item. WSDL 2.0 modifies the XML Schema definition of the xs:schema element information item to make this attribute information item required. The targetNamespace attribute information item has the following Infoset properties: • A [local name] of targetNamespace. • A [namespace name] which has no value. The type of the targetNamespace attribute information item is xs:anyURI. 3.1.3 References to Element Declarations and Type Definitions Whether inlined or imported, the element declarations present in a schema may be referenced from an Interface Message Reference or Interface Fault component. Similarly, regardless of whether they are inlined or imported, the type definitions present in a schema may be referenced from a Property component. A named, global xs:element declaration may be referenced from the element attribute information item of an input , output or fault element information item. The QName is constructed from the targetNamespace of the schema and the value of the name attribute information item of the xs:element element information item. An element attribute information item MUST NOT refer to a global xs:simpleType or xs:complexType definition. A named, global xs:simpleType or xs:complexType declaration may be referenced from the constraint attribute information item of property element information item. The QName is constructed from the targetNamespace of the schema and the value of the name attribute information item of the xs:simpleType or xs:complexType element information item. A constraint attribute information item MUST NOT refer to a global xs:element definition. 3.2 Using Other Schema Languages Since it is unreasonable to expect that a single schema language can be used to describe all possible Interface Message Reference, Interface Fault and Property component contents and their constraints, WSDL 2.0 allows alternate schema languages to be specified via extensibility elements. An extensibility element information item MAY appear under the types element information item to identify the schema language employed, and to locate the schema instance defining the grammar for Interface Message Reference and Interface Fault components or the constraint for Property components. Depending upon the schema language used, an element information item MAY be defined to allow inlining, if and only if the schema language can be expressed in XML. A specification of extension syntax for an alternative schema language MUST include the declaration of an element information item, intended to appear as a child of the wsdl:types element information item, which references, names, and locates the schema instance (an “import” element information item). The extension specification SHOULD, if necessary, define additional properties of the Description component (and extensibility attributes) to hold the components of the referenced type system. It is expected that additional extensibility attributes for Interface Message Reference, Interface Fault and Property components will also be defined, along with a mechanism for resolving the values of those attributes to a particular imported type system component. See [Alternative Schema Languages Support] for examples of using other schema languages. These examples reuse the {element declarations} property of the Description component and the element attribute information items of the wsdl:input , wsdl:output and wsdl:fault element information items. Note: This specification does not define the behavior of a WSDL 2.0 document that uses multiple schema languages for describing type system components simultaneously. 3.3 Describing Messages that Refer to Services and Endpoints Web services may exchange messages that refer to other Web services or Web service endpoints. If the interface or binding of these referenced services or endpoints are known at description time, then it may be useful to include this information in the WSDL 2.0 document that describes the Web service. WSDL 2.0 provides two global attribute information items, wsdlx:interface and wsdlx:binding that may be used to annotate XML Schema components or components from other type description languages. WSDL 2.0 also defines the use of these global attribute information items to annotate XML Schema components that use the xs:anyURI simple type in an element information item or attribute information item for endpoint addresses that correspond to the {address} property of the Endpoint component. See the primer [WSDL 2.0 Primer] for more information and examples. 3.3.1 wsdlx:interface attribute information item WSDL 2.0 provides a global attribute information item with the following Infoset properties: • A [local name] of interface . • A [namespace name] of " http://www.w3.org/2005/08/wsdl-extensions ". The type of the wsdlx:interface attribute information item is an xs:QName that specifies the {name} property of an Interface component. 3.3.2 wsdlx:binding attribute information item WSDL 2.0 provides a global attribute information item with the following Infoset properties: • A [local name] of binding . • A [namespace name] of " http://www.w3.org/2005/08/wsdl-extensions ". The type of the wsdlx:binding attribute information item is an xs:QName that specifies the {name} property of an Binding component. 3.3.3 wsdlx:interface and wsdlx:binding Consistency The wsdlx:interface and wsdlx:binding attributes may be used either independently or together. If they are used together then they MUST satisfy the same consistency rules that apply to the {interface} property of a Service component and the {binding} property of a nested Endpoint component, that is either the binding refers the interface or the binding refers to no interface. 3.3.4 Use of wsdlx:interface and wsdlx:binding with xs:anyURI wsdlx:interface and wsdlx:binding may be used to describe element information items and attribute information items whose type is xs:anyURI or a restriction of it, to describe messages that contain the {address} property of an Endpoint. This is accomplished by including the wsdlx:interface and/or wsdlx:binding attribute information item in the xs:element , xs:simpleType , or xs:attribute element information item of the corresponding XML Schema component. 4. Modularizing WSDL 2.0 descriptions This specification provides two mechanisms, described in this section, for modularizing WSDL 2.0 descriptions. These mechanisms help to make WSDL 2.0 descriptions clearer by allowing separation of the various components of a description. Such separation could be performed according to the level of abstraction of a given set of components, or according to the namespace affiliation required of a given set of components or according to some other grouping such as application applicability. Both mechanisms work at the level of WSDL 2.0 components and NOT at the level of XML Information Sets or XML 1.0 serializations. 4.1 Including Descriptions * The WSDL 2.0 include element information item allows for the separation of different components of a service definition, belonging to the same target namespace, into independent WSDL 2.0 documents. The WSDL 2.0 include element information item is modeled after the XML Schema include element information item (see [XML Schema: Structures], section 4.2.3 "References to schema components in the same namespace"). Specifically, it can be used to include components from WSDL 2.0 descriptions that share a target namespace with the including description. Components in the transitive closure of the included WSDL 2.0 documents become part of the Description component of the including WSDL 2.0 document. The included components can be referenced by QName. Note that because all WSDL 2.0 descriptions have a target namespace, no-namespace includes (sometimes known as “chameleon includes”) never occur in WSDL 2.0. A mutual include is direct inclusion by one WSDL 2.0 document of another WSDL 2.0 document which includes the first. A circular include achieves the same effect with greater indirection (A s B includes C includes A, for instance). Multiple inclusion of a single WSDL 2.0 document resolves to a single set of components. Mutual, multiple, and circular includes are explicitly permitted, and do not represent multiple redefinitions of the same components. Multiple inclusion of a single WSDL 2.0 document has the same meaning as including it only once. The include element information item has: • A [local name] of include . • A [namespace name] of "http://www.w3.org/2005/08/wsdl". • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED location attribute information item as described below in 4.1.1 location attribute information item with include [owner element]. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information item amongst its [children], as follows: □ Zero or more documentation element information items (see 5. Documentation). □ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 4.1.1 location attribute information item with include [owner element] The location attribute information item has the following Infoset properties: • A [local name] of location . • A [namespace name] which has no value. A location attribute information item is of type xs:anyURI . Its actual value is the location of some information about the namespace identified by the targetNamespace attribute information item of the containing description element information item. It is an error if the IRI indicated by location does not resolve to a WSDL 2.0 document. The actual value of the targetNamespace attribute information item of the included WSDL 2.0 document MUST match the actual value of the targetNamespace attribute information item of the description element information item which is the [parent] of the include element information item. 4.2 Importing Descriptions * Every top-level WSDL 2.0 component is associated with a target namespace. On its ws:description element information item, WSDL 2.0 documents carries a targetNamespace attribute information item that associates the document with a target namespace. This section describes the syntax and mechanisms by which references may be made from within a WSDL 2.0 document to components not within the document's target namespace. In addition to this syntax, there is an optional facility for suggesting the IRI of a WSDL 2.0 document containing definition components from that foreign target namespace. The WSDL 2.0 import element information item is modeled after the XML Schema xs:import element information item (see [XML Schema: Structures], section 4.2.3 "References to schema components across namespaces"). Specifically, it can be used to import components from WSDL descriptions that do not share a target namespace with the importing document. The WSDL 2.0 ws:import element information item identifies namespaces used in foreign references. The existence of the WSDL 2.0 ws:import element information item signals that the WSDL 2.0 document may contain references to foreign components. The ws:import element information item is therefore like a forward declaration for other namespaces. As with XML schema, each WSDL 2.0 document making references to components in a given (foreign) namespace MUST have an import element information item for that namespace (but not necessarily providing a location attribute information item identifying the WSDL 2.0 document in which the referenced component is declared). In other respects, the visibility of components is pervasive; if two WSDL 2.0 documents import the same namespace then they will have access to the same components from the imported namespace (i.e. regardless of which, if any, location attribute information item values are provided on the respective import element information items.) Using the import element information item is a necessary condition for making components from another namespace available to a WSDL 2.0 document. That is, a WSDL 2.0 document can only refer to components in a namespace other than its own target namespace if the WSDL 2.0 document contains an import element information item for that foreign namespace. This specification does not preclude repeating the import element information item for the same value of the namespace attribute information item as long as they provide different values for the location attribute information item. Repeating the import element information item for the same namespace value MAY be used as a way to provide alternate locations to find information about a given namespace. Furthermore, this specification DOES NOT require the location attribute information item to be dereferenceable. If it is not dereferenceable then no information about the imported namespace is provided by that import element information item. It is possible that such lack of information can cause QNames in other parts of a WSDL 2.0 Description component to become broken references (see 2.19 QName resolution). Such broken references are not errors of the import element information item but rather QName resolution errors which must be detected as described in 2.19 QName resolution. The import element information item has the following Infoset properties: • A [local name] of import . • A [namespace name] of "http://www.w3.org/2005/08/wsdl". • One or more attribute information items amongst its [attributes] as follows: □ A REQUIRED namespace attribute information item as described below in 4.2.1 namespace attribute information item. □ An OPTIONAL location attribute information item as described below in 4.2.2 location attribute information item with import [owner element]. □ Zero or more namespace qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". • Zero or more element information items amongst its [children], as follows: □ Zero or more documentation element information items (see 5. Documentation). □ Zero or more namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl". 4.2.1 namespace attribute information item The namespace attribute information item has the following Infoset properties: • A [local name] of namespace . • A [namespace name] which has no value. The namespace attribute information item is of type xs:anyURI . Its actual value indicates that the containing WSDL 2.0 document MAY contain qualified references to WSDL 2.0 definitions in that namespace (via one or more prefixes declared with namespace declarations in the normal way). This value MUST NOT match the actual value of targetNamespace attribute information item in the enclosing WSDL 2.0 document. If the location attribute in the import element information item references a WSDL 2.0 document, then the actual value of the namespace attribute information item MUST be identical to the actual value of the targetNamespace attribute information item in the referenced WSDL 2.0 document. 4.2.2 location attribute information item with import [owner element] The location attribute information item has the following Infoset properties: • A [local name] of location . • A [namespace name] which has no value. The location attribute information item is of type xs:anyURI . Its actual value, if present, gives a hint as to where a serialization of a WSDL 2.0 document with definitions for the imported namespace can be found. The location attribute information item is optional. This allows WSDL 2.0 components to be constructed from information other than serialized XML 1.0 or a WSDL 2.0 document. It also allows the development of WSDL 2.0 processors that have a prior (i.e., built-in) knowledge of certain namespaces. 5. Documentation [extension elements]* WSDL 2.0 uses the optional documentation element information item as a container for human readable and/or machine processable documentation. The content of the element information item is arbitrary character information items and element information items ("mixed" content in XML Schema[XML Schema: Structures]). The documentation element information item is allowed inside any WSDL 2.0 element information item. Like other element information items in the "http://www.w3.org/2005/08/wsdl" namespace, the documentation element information item allows qualified attribute information items whose [namespace name] is not "http://www.w3.org/ 2005/08/wsdl". The xml:lang attribute (see [XML 1.0]) MAY be used to indicate the language used in the contents of the documentation element information item . The documentation element information item has: • A [local name] of documentation . • A [namespace name] of "http://www.w3.org/2005/08/wsdl". • Zero or more attribute information items in its [attributes] property. • Zero or more child element information items in its [children] property. • Zero or more character information items in its [children] property. 6. Language Extensibility In addition to extensibility implied by the Feature and Property components described above, the schema for WSDL 2.0 has a two-part extensibility model based on namespace-qualified elements and attributes. An extension is identified by the QName consisting of its namespace IRI and its element name. The meaning of an extension SHOULD be defined (directly or indirectly) in a document that is available at its namespace IRI. 6.1 Element based Extensibility WSDL 2.0 allows extensions to be defined in terms of element information items. Where indicated herein, WSDL 2.0 allows namespace-qualified element information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl" to appear among the [children] of specific element information items whose [namespace name] is "http://www.w3.org/2005/08/wsdl". Such element information items MAY be used to annotate WSDL 2.0 constructs such as interface, operation, etc. It is expected that extensions will want to add to the existing properties of components in the component model. The specification for an extension element information item should include definitions of any such properties and the mapping from the XML representation of the extension to the properties in the component model. The WSDL 2.0 schema also defines a base type for use by extensibility elements. Example 6-1 shows the type definition. The use of this type as a base type is optional. The element declarations which serve as the heads of the defined substitution groups are all of type "xs:anyType". Extensibility elements are commonly used to specify some technology-specific binding. They allow innovation in the area of network and message protocols without having to revise the base WSDL 2.0 specification. WSDL 2.0 recommends that specifications defining such protocols also define any necessary WSDL 2.0 extensions used to describe those protocols or formats. Example 6-1. Base type for extensibility elements 6.1.1 Mandatory extensions Extension elements can be marked as mandatory by annotating them with a wsdl:required attribute information item (see 6.1.2 required attribute information item) with a value of "true". A mandatory extension is an extension that MAY change the meaning of the element to which it is attached, such that the meaning of that element is no longer governed by this specification. Instead, the meaning of an element containing a mandatory extension is governed by the meaning of that extension. Thus, the definition of the element's meaning is delegated to the specification that defines the extension. An extension that is NOT marked as mandatory MUST NOT invalidate the meaning of any part of the WSDL 2.0 document. Thus, a NON-mandatory extension merely provides additional description of capabilities of the service. This specification does not provide a mechanism to mark extension attributes as being required. Therefore, all extension attributes are NON-mandatory. Note: A mandatory extension is considered mandatory because it has the ability to change the meaning of the element to which it is attached. Thus, the meaning of the element may not be fully understood without understanding the attached extension. A NON-mandatory extension, on the other hand, can be safely ignored without danger of misunderstanding the rest of the WSDL 2.0 document. If a WSDL 2.0 document declares an extension, Feature or Property as optional (i.e., NON-mandatory), then the Web service MUST NOT assume that the client supports that extension, Feature or Property, unless the Web service knows (through some other means) that the client has in fact elected to engage and support that extension, Feature or Property. Note: A key purpose of an extension is to formally indicate (i.e., in a machine-processable way) that a particular feature or convention is supported or required. This enables toolkits that understand the extension to engage it automatically, while toolkits that do not yet understand a required extension may be able to flag it to an operator for manual support. If a Web service requires the client to follow a particular convention that is likely to be automatable in WSDL 2.0 toolkits, then that convention SHOULD be indicated in the WSDL 2.0 document as a wsdl:required extension, rather than just being conveyed out of band, even if that convention is not currently implemented in WSDL 2.0 toolkits. This practice will help prevent interoperability problems that could arise if one toolkit requires a particular convention that is not indicated in the WSDL 2.0 document, while another toolkit does not realize that that convention is required. It will also help facilitate future automatic processing by WSDL 2.0 toolkits. On the other hand, a client MAY engage an extension, Feature or Property that is declared as optional in the WSDL 2.0 document. Therefore, the Web service MUST support every extension, Feature or Property that is declared as optional in the WSDL 2.0 document, in addition to supporting every extension, Feature or Property that is declared as mandatory. Note: If finer-grain, direction-sensitive control of extensions, Features or Properties is desired, then such extensions, Features or Properties may be designed in a direction-sensitive manner (from the client or from the Web service) so that either direction may be separately marked required or optional. For example, instead of defining a single extension that governs both directions, two extensions could be defined -- one for each direction. 6.1.2 required attribute information item WSDL 2.0 provides a global attribute information item with the following Infoset properties: • A [local name] of required . • A [namespace name] of "http://www.w3.org/2005/08/wsdl". The type of the required attribute information item is xs:boolean. Its default value is "false" (hence extensions are NOT required by default). 6.2 Attribute-based Extensibility WSDL 2.0 allows qualified attribute information items whose [namespace name] is NOT "http://www.w3.org/2005/08/wsdl" to appear on any element information item whose namespace name IS "http://www.w3.org/2005/08/wsdl". Such attribute information items can be used to annotate WSDL 2.0 constructs such as interfaces, bindings, etc. WSDL 2.0 does not provide a mechanism for marking extension attribute information items as mandatory. 6.3 Extensibility Semantics As indicated above, it is expected that the presence of extensibility elements and attributes will result in additional properties appearing in the component model. The presence of an optional extensibility element or attribute MAY therefore augment the semantics of a WSDL 2.0 document in ways that do not invalidate the existing semantics. However, the presence of a mandatory extensibility element MAY alter the semantics of a WSDL 2.0 document in ways that invalidate the existing semantics. Extensibility elements SHOULD NOT alter the existing semantics in ways that are likely to confuse users. Note: However, once the client and service both know that an optional feature has been engaged (because the service has received a message explicitly engaging that feature, for example), then the semantics of that feature supercede what the WSDL 2.0 document indicated. For example, the WSDL 2.0 document may have specified an XML message schema to be used, but also indicated an optional security feature that encrypts the messages. If the security feature is engaged, then the encrypted messages will no longer conform to the specified message schema (until they are decrypted). Note: Authors of extensibility elements should make sure to include in the specification for such elements a clear statement of the requirements for document conformance (see 1.2 Document Conformance). 7. Locating WSDL 2.0 Documents As an XML vocabulary, WSDL documents, WSDL fragments or references to WSDL components -via QNames- MAY appear within other XML documents. This specification defines a global attribute, wsdlLocation , to help with QName resolution (see 2.19 QName resolution). This attribute allows an element that contains such references to be annotated to indicate where the WSDL for a namespace (or set of namespaces) can be found. In particular, this attribute is expected to be useful when using service references in message exchanges. The wsdlLocation global attribute is defined in the namespace "http:// www.w3.org/2005/08/wsdl-instance" (hereafter referred to as "wsdli:wsdlLocation", for brevity). This attribute MAY appear on any XML element which allows attributes from other namespaces to occur. It MUST NOT appear on a wsdl:description element or any of its children/descendants. A normative XML Schema [XML Schema: Structures], [XML Schema: Datatypes] document for the "http://www.w3.org/2005/08/wsdl-instance" namespace can be found at http://www.w3.org/2005/08/wsdl-instance. 7.1 wsdli:wsdlLocation attribute information item WSDL 2.0 provides a global attribute information item with the following Infoset properties: • A [local name] of wsdlLocation . • A [namespace name] of "http://www.w3.org/2005/08/wsdl-instance". The type of the wsdlLocation attribute information item is a list xs:anyURI (of even length). Its actual value MUST be a list of pairs of IRIs; where the first IRI of a pair, which MUST be an absolute IRI as defined in [IETF RFC 3987], indicates a WSDL 2.0 (or 1.1) namespace name, and, the second a hint as to the location of a WSDL 2.0 document defining WSDL 2.0 components (or WSDL 1.1 elements [WSDL 1.1]) for that namespace name. The second IRI of a pair MAY be absolute or relative. 8. Conformance 8.1 XML Information Set Conformance This specification conforms to the [XML Information Set]. The following information items MUST be present in the input Infosets to enable correct processing of WSDL 2.0 documents: • Document Information Items with [children] and [base URI] properties. • Element Information Items with [namespace name], [local name], [children], [attributes], [base URI] and [parent] properties. • Attribute Information Items with [namespace name], [local name] and [ normalized value] properties. • Character Information Items with [character code], [element content whitespace] and [parent] properties. 9.

The application/wsdl+xml Media Type This appendix defines the "application/wsdl+xml" media type which can be used to describe WSDL 2.0 documents serialized as XML. A.1 Registration MIME media type name: application MIME subtype name: wsdl+xml Required parameters: none Optional parameters: charset This parameter has identical semantics to the charset parameter of the "application/xml" media type as specified in [RFC 3023]. Encoding considerations: Identical to those of "application/xml" as described in [RFC 3023], section 3.2, as applied to the WSDL document Infoset. Security considerations: See section A.3 Security considerations. Interoperability considerations: There are no known interoperability issues. Published specifications: This document and [WSDL 2.0 Adjuncts]. Applications which use this media type: No known applications currently use this media type. Additional information: File extension: wsdl Fragment identifiers: Either a syntax identical to that of "application/xml" as described in [RFC 3023], section 5 or the syntax defined in A.2 Fragment Identifiers . Base URI: As specified in [RFC 3023], section 6. Macintosh File Type code: WSDL Person and email address to contact for further information: World Wide Web Consortium Intended usage: COMMON Author/Change controller: The WSDL 2.0 specification set is a work product of the World Wide Web Consortium's Web Service Description Working Group. The W3C has change control over these specifications. A.2 Fragment Identifiers This section defines a fragment identifier syntax for identifying components of a WSDL 2.0 document. This fragment identifier syntax is compliant with the [ XPointer Framework]. A WSDL 2.0 fragment identifier consists of zero or more xmlns pointer parts followed by a pointer part as defined below. The pointer parts have a scheme name that corresponds to one of the standard WSDL 2.0 component types, and scheme data that is a path composed of names that identify the components. The scheme names all begin with the prefix "wsdl." to avoid name conflicts with other schemes. The names in the path are of type either QName, NCName, IRI, URI, or Pointer Part depending on the context. For QNames, any prefix MUST be defined by a preceding xmlns pointer part. If a QName does not have a prefix then its namespace name is the target namespace of the WSDL 2.0 document. The fragment identifier is typically constructed from the {name} property of the component and the {name} properties of its ancestors as a path according to Table A-1. The first column of this table gives the name of the WSDL 2.0 component. Columns labeled 1 through 4 specify the identifiers that uniquely identify the component within its context. Identifiers are typically formed from the {name} property, although in several cases references to other components are used. These identifiers are then used to construct the pointer part in the last column. Table A-1.

IRI References for WSDL 2.0 Components (Non-Normative) This appendix provides a syntax for IRI references for all components found in a WSDL 2.0 document. The IRI references are easy to understand and compare, while imposing no burden on the WSDL 2.0 author. C.1 WSDL 2.0 IRIs There are two main cases for WSDL 2.0 IRIs: • the IRI of a WSDL 2.0 document • the IRI of a WSDL 2.0 namespace The IRI of a WSDL 2.0 document can be dereferenced to give a resource representation that contributes component definitions to a single WSDL 2.0 namespace. If the media type is set to the WSDL 2.0 media type, then the fragment identifiers can be used to identify the main components that are defined in the document. However, in keeping with the recommendation in 2.1.1 The Description Component that the namespace URI be dereferencible to a WSDL 2.0 document, this appendix specifies the use of the namespace IRI with the WSDL 2.0 fragment identifiers to form a IRI-reference. The IRI in a IRI-reference for a WSDL 2.0 component is the namespace name of the {name} property of either the component itself, in the case of Interface, Binding, and Service components, or the {name} property of the ancestor top-level component. The IRI provided by the namespace name of the {name} property is combined with a fragment identifier as defined in A.2 Fragment Identifiers. C.2 Example Consider the following WSDL 2.0 document located at http://example.org/ TicketAgent.wsdl: Example C-1. IRI References - Example WSDL 2.0 Document Its components have the following IRI-references: Example C-2.
