Abstract

This specification defines the Document Object Model Validation Level 3, a platform- and language-neutral interface. This module provides the guidance to programs and scripts to dynamically update the content and the structure of documents while ensuring that the document remains valid, or to ensure that the document becomes valid.

Status of this document

This section describes the status of this document at the time of its publication. Other documents may supersede this document. The latest status of this document series is maintained at the W3C.

This is the Candidate Recommendation specification of "DOM Level 3 Validation". This version is based on the feedback during the Last Call period. The DOM Working Group expects to request that the Director advance this specification to Proposed Recommendation after the DOM Working Group documents two interoperable implementations of at least one normative binding. Basic tests of features of this specification will be produced and used in this effort. The two implementations must be produced by different organizations. The estimated end of the Candidate Recommendation period is 31 August 2003. Comments on this document are invited and are to be sent to the public mailing list www-dom@w3.org, before the end of the review period. An archive is available at http://lists.w3.org/Archives/Public/www-dom/.

Individuals or organizations are also invited to send a message to the public mailing list if they intend to produce an implementation of this module. The implementation report is also available.

This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to use W3C Working Drafts as reference material or to cite them as other than "work in progress". This is work in progress and does not imply endorsement by, or the consensus of, either W3C or participants of the DOM working group.

This document has been produced as part of the W3C DOM Activity. The authors of this document are the DOM Working Group participants.

Patent disclosures relevant to this specification may be found on the Working Group's patent disclosure page.

Table of contents

1.1 Overview

This chapter describes the optional DOM Level 3 Validation feature. This module provides APIs to guide construction and editing of XML documents. Examples of such guided editing are queries of the nature that combine questions like "what does the schema allow me to insert/delete here?" and "if I insert/delete here, will the document still be valid?".

Users may also want to know several levels of details, e.g., all the possible children, those which would be valid given what precedes this point, lists of defined symbols of a given kind, in order to help in editing and creating an XML document. Some of these queries would prompt checks and warn you if you're about to conflict with or overwrite such data.

Finally, users would like to validate an edited or newly constructed document before serializing it or passing it to other users. To some, they may edit, come up with an invalid document, then edit again to result in a valid document. During this process, these APIs can allow the user to check the validity of the document or sub-tree on demand; and if needed can also require that the document or sub-tree remain valid during this editing process via the DocumentEditVAL.continuousValidityChecking flag.

A DOM application can use the hasFeature(feature, version) method of the DOMImplementation interface to determine with parameter values "Validation" and "3.0", respectively, whether or not these interfaces are supported by the implementation. In order to fully support this feature, an implementation must also support the "Core" feature defined in [DOM Level 2 Core] or newer. The requirements for conformance to a DOM Level 3 module is defined in the conformance section of [DOM Level 3 Core].

This chapter focuses on the editing aspects used in the XML document editing world and usage of such information. The appendix describes in detail all the possible outcomes of the validation operations on the different node types.

1.2 Exceptions

This section describes the "VAL-DOC-EDIT" exceptions.

Exception ExceptionVAL

Some Validation operations may throw an ExceptionVAL as described in their descriptions.


IDL Definition
exception ExceptionVAL {
  unsigned short   code;
};
// ExceptionVALCode
const unsigned short      NO_SCHEMA_AVAILABLE_ERR        = 71;

Definition group ExceptionVALCode

An integer indicating the type of error generated.

Defined Constants
NO_SCHEMA_AVAILABLE_ERR
This error occurs when the operation cannot complete due to an unavailable schema.

1.3 Document Editing Interfaces

This section contains "Document Editing" methods as described in the DocumentEditVAL, NodeEditVAL, ElementEditVAL, and CharacterDataEditVAL interfaces.

Interface DocumentEditVAL

This interface extends the NodeEditVAL interface with additional methods for document editing. An object implementing this interface must also implement the Document interface.


IDL Definition
interface DocumentEditVAL : NodeEditVAL {
           attribute boolean         continuousValidityChecking;
                                        // raises(DOMException, 
                                        //        ExceptionVAL, 
                                        //        DOMException) on setting

  readonly attribute DOMConfiguration config;
  NameList           getDefinedElements(in DOMString namespaceURI);
  unsigned short     validateDocument();
};

Attributes
config of type DOMConfiguration, readonly
This allows the setting of the error handler, as described in the [DOM Level 3 Core] DOMConfiguration interface.
continuousValidityChecking of type boolean
An attribute specifying whether the validity of the document is continuously enforced. When the attribute is set to true, the implementation may raise certain exceptions, depending on the situation (see the following). This attribute is false by default.
Exceptions on setting

DOMException

NOT_SUPPORTED_ERR: Raised if the implementation does not support setting this attribute to true.

ExceptionVAL

NO_SCHEMA_AVAILABLE_ERR: Raised if this attribute is set to true and a schema is unavailable.

DOMException

VALIDATION_ERR: Raised if an operation makes this document not compliant with the VAL_INCOMPLETE validity type or the document is invalid, and this attribute is set to true.

Methods
getDefinedElements
Returns list of all element information item names of global declaration, belonging to the specified namespace.
Parameters
namespaceURI of type DOMString
namespaceURI of namespace. For DTDs, this is null.
Return Value

NameList

List of all element information item names belonging to the specified namespace or null if no schema is available.

No Exceptions
validateDocument
Validates the document against the schema, e.g., a DTD or an XML Schema or another. Any attempt to modify any part of the document while validating results in implementation-dependent behavior. In addition, the validation operation itself cannot modify the document, e.g., for default attributes. This method makes use of the error handler, as described in the [DOM Level 3 Core] DOMConfiguration interface, with all errors being SEVERITY_ERROR as defined in the DOMError interface.
Return Value

unsigned short

A validation state constant.

No Parameters
No Exceptions
Interface NodeEditVAL

This interface is similar to the [DOM Level 3 Core] Node interface, with methods for guided document editing.


IDL Definition
interface NodeEditVAL {

  // validationType
  const unsigned short      VAL_WF                         = 1;
  const unsigned short      VAL_NS_WF                      = 2;
  const unsigned short      VAL_INCOMPLETE                 = 3;
  const unsigned short      VAL_SCHEMA                     = 4;


  // validationState
  const unsigned short      VAL_TRUE                       = 5;
  const unsigned short      VAL_FALSE                      = 6;
  const unsigned short      VAL_UNKNOWN                    = 7;

  readonly attribute DOMString       defaultValue;
  readonly attribute DOMStringList   enumeratedValues;
  unsigned short     canInsertBefore(in Node newChild, 
                                     in Node refChild);
  unsigned short     canRemoveChild(in Node oldChild);
  unsigned short     canReplaceChild(in Node newChild, 
                                     in Node oldChild);
  unsigned short     canAppendChild(in Node newChild);
  unsigned short     nodeValidity(in unsigned short valType);
};

Definition group validationType

An integer indicating the validation type. Other specifications can define stricter validation types/constants by extending the NodeEditVAL interface.

Defined Constants
VAL_INCOMPLETE
Check if the node's immediate children are those expected by the content model. This node's trailing required children could be missing. It includes VAL_NS_WF.
VAL_NS_WF
Check if the node is namespace well-formed.
VAL_SCHEMA
Check if the node's entire subtree are those expected by the content model. It includes VAL_NS_WF.
VAL_WF
Check if the node is well-formed.
Definition group validationState

An integer indicating the validation state, or whether the operation can or cannot be done.

Defined Constants
VAL_FALSE
False if the node is invalid with regards to the operation, or if the operation cannot be done.
VAL_TRUE
True if the node is valid with regards to the operation, or if the operation can be done.
VAL_UNKNOWN
The validity of the node is unknown.
Attributes
defaultValue of type DOMString, readonly
The default value specified in an attribute or an element declaration or null if unspecified. If the schema is an XML Schema, this is the canonical lexical representation of the default value.
enumeratedValues of type DOMStringList, readonly
A DOMStringList, as described in [DOM Level 3 Core], of distinct values for an attribute or an element declaration or null if unspecified. If the schema is an XML Schema, this is a list of strings which are lexical representations corresponding to the values in the [value] property of the enumeration component for the type of the attribute or element. It is recommended that the canonical lexical representations of the values be used.
Methods
canAppendChild
Determines whether the Node.appendChild operation would make this document not compliant with the VAL_INCOMPLETE validity type.
Parameters
newChild of type Node
Node to be appended.
Return Value

unsigned short

A validation state constant.

No Exceptions
canInsertBefore
Determines whether the Node.insertBefore operation would make this document not compliant with the VAL_INCOMPLETE validity type.
Parameters
newChild of type Node
Node to be inserted.
refChild of type Node
Reference Node.
Return Value

unsigned short

A validation state constant.

No Exceptions
canRemoveChild
Determines whether the Node.removeChild operation would make this document not compliant with the VAL_INCOMPLETE validity type.
Parameters
oldChild of type Node
Node to be removed.
Return Value

unsigned short

A validation state constant.

No Exceptions
canReplaceChild
Determines whether the Node.replaceChild operation would make this document not compliant with the VAL_INCOMPLETE validity type.
Parameters
newChild of type Node
New Node.
oldChild of type Node
Node to be replaced.
Return Value

unsigned short

A validation state constant.

No Exceptions
nodeValidity
Determines if the node is valid relative to the validation type specified in valType. This operation doesn't normalize before checking if it is valid. To do so, one would need to explicitly call a normalize method. The difference between this method and the DocumentEditVAL.validateDocument() method is that the latter method only checks to determine whether the entire document is valid.
Parameters
valType of type unsigned short
Flag to indicate the validation type checking to be done.
Return Value

unsigned short

A validation state constant.

No Exceptions
Interface ElementEditVAL

This interface extends the NodeEditVAL interface with additional methods for guided document editing. An object implementing this interface must also implement the Element interface.

This interface also has attributes that are a NameList of elements or attributes which can appear in the specified context. Some schema languages, i.e., XML Schema, define wildcards which provide for validation of attribute and element information items dependent on their namespace names but independent of their local names.

To expose wildcards, the NameList returns the values that represent the namespace constraint:

  • {namespaceURI, name} is {null, ##any} if any;
  • {namespaceURI, name} is {namespace_a, ##other} if not and a namespace name (namespace_a);
  • {namespaceURI, name} is {null, ##other} if not and absent;
  • Pairs of {namespaceURI, name} with values {a_namespaceURI | null, null} if a set whose members are either namespace names or absent.

IDL Definition
interface ElementEditVAL : NodeEditVAL {

  // ContentTypeVAL
  const unsigned short      VAL_EMPTY_CONTENTTYPE          = 1;
  const unsigned short      VAL_ANY_CONTENTTYPE            = 2;
  const unsigned short      VAL_MIXED_CONTENTTYPE          = 3;

                                     in DOMString attrval);
  unsigned short     canSetAttributeNode(in Attr attrNode);
  unsigned short     canSetAttributeNS(in DOMString namespaceURI, 
                                       in DOMString qualifiedName,

  unsigned short     isElementDefinedNS(in DOMString namespaceURI, 
                                        in DOMString name);
};

Definition group ContentTypeVAL

An integer indicating the content type of an element.

Defined Constants
VAL_ANY_CONTENTTYPE
The content model contains unordered child information item(s), i.e., element, processing instruction, unexpanded entity reference, character, and comment information items as defined in the [XML Information set]. If the schema is a DTD, this corresponds to the ANY content model.
VAL_ELEMENTS_CONTENTTYPE
The content model contains a sequence of element information items optionally separated by whitespace. If the schema is a DTD, this is the element content content model; and if the schema is an XML Schema, this is the element-only content type.
VAL_EMPTY_CONTENTTYPE
The content model does not allow any content. If the schema is an XML Schema, this corresponds to the empty content type; and if the schema is a DTD, this corresponds to the EMPTY content model.
VAL_MIXED_CONTENTTYPE
The content model contains a sequence of ordered element information items optionally interspersed with character data. If the schema is an XML Schema, this corresponds to the mixed content type.
VAL_SIMPLE_CONTENTTYPE
The content model contains character information items. If the schema is an XML Schema, then the element has a content type of VAL_SIMPLE_CONTENTTYPE if the type of the element is a simple type definition, or the type of the element is a complexType whose {content type} is a simple type definition.
Attributes
allowedAttributes of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of all possible attribute information items or wildcards that can appear as attributes of this element, or null if this element has no context or schema. Duplicate pairs of {namespaceURI, name} are eliminated.
allowedChildren of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of all possible element information items or wildcards that can appear as children of this element, or null if this element has no context or schema. Duplicate pairs of {namespaceURI, name} are eliminated.
allowedFirstChildren of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of all possible element information items or wildcards that can appear as a first child of this element, or null if this element has no context or schema. Duplicate pairs of {namespaceURI, name} are eliminated.
allowedNextSiblings of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of all possible element information items or wildcards that can appear as a next sibling of this element, or null if this element has no context or schema. Duplicate pairs of {namespaceURI, name} are eliminated.
allowedParents of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of all possible element information items that can appear as a parent this element, or null if this element has no context or schema.
allowedPreviousSiblings of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of all possible element information items or wildcards that can appear as a previous sibling of this element, or null if this element has no context or schema.
contentType of type unsigned short, readonly
The content type of an element as defined above.
requiredAttributes of type NameList, readonly
A NameList, as described in [DOM Level 3 Core], of required attribute information items that must appear on this element, or null if this element has no context or schema.

Interface CharacterDataEditVAL

This interface extends the NodeEditVAL interface with additional methods for document editing. An object implementing this interface must also implement CharacterData interface. When validating CharacterData nodes, the NodeEditVAL.nodeValidity(valType) operation must find the nearest parent node in order to do this; if no parent node is found, NodeEditVAL.VAL_UNKNOWN is returned. In addition, when NodeEditVAL.VAL_INCOMPLETE is passed in as an argument to the NodeEditVAL.nodeValidity operation to operate on such nodes, the operation considers all the text and not just some of it.

Appendix A: Validation Outcomes

Editor:
Ben Chang, Oracle

Table of contents

A.1 The nodeValidity and validateDocument methods

The following table describes all possible validation outcomes of the NodeEditVAL.nodeValidity(valType) method.

Validation Type Validity outcome
VAL_TRUE VAL_FALSE VAL_UNKNOWN
VAL_WF The node is well-formed. The node is not well-formed. Not applicable.
VAL_NS_WF The node is well-formed. Processor must take into account all the in-scope namespace declarations. The node is not namespace well-formed. Processor must take into account all the in-scope namespace declarations. Not applicable.
VAL_NS_WF The node is well-formed. Processor must take into account all namespace declarations in scope. The node is not namespace well-formed. Processor must take into account all the in-scope namespace declarations. Not applicable.
VAL_SCHEMA The node is valid: it complies with all the constraints expressed in the schema. The node fails to comply to all the constraints expressed in the schema. If the schema is an XML Schema, PSVI [validity] property value is unknown.
VAL_INCOMPLETE The node is valid: it complies with the VAL_INCOMPLETE definition. The node is invalid with regard to the VAL_INCOMPLETE definition. If the schema is an XML Schema, PSVI [validity] property value is unknown.

The following table describes the outcome of the DocumentEditVAL.validateDocument() and NodeEditVAL.nodeValidity(valType) methods, with the latter called on the DocumentEditVAL node with validationType NodeEditVAL.VAL_SCHEMA.

Methods Validity outcome
VAL_TRUE VAL_FALSE VAL_UNKNOWN
validateDocument and nodeValidity, called on the Document node with validationType VAL_SCHEMA. If the schema is a DTD, then the document valid constraint is satisfied. If the schema is an XML Schema, then the document validity is the same as the validity of the validation root, i.e., documentElement: PSVI [validity] valid. Fails to satisfy the constraints defined. If the schema is an XML Schema, then schema is not found or the declaration for the validation root is not found: PSVI [validity] unknown.

The following table describes outcomes for the NodeEditVAL.nodeValidity(valType) method called with the validationType NodeEditVAL.VAL_SCHEMA:

Node types Validity outcome
VAL_TRUE VAL_FALSE VAL_UNKNOWN
Element If the schema is a DTD, then element and attribute validity constraints, including attribute validity constraint defined below are satisfied. If the schema is an XML Schema, then PSVI [validity] valid. Fails to satisfy the constraints defined. If the schema is an XML Schema, then PSVI [validity] unknown.
Attr If the schema is a DTD, then all validity constraints defined in section 3.3.1, "Attribute Type", required and fixed attribute are satisfied. If the schema is an XML Schema, then PSVI [validity] valid. Fails to satisfy the constraints defined. If the schema is an XML Schema, then PSVI [validity] unknown.
Text The node is well-formed. The node is not well-formed. If no parent node is found.
CDATASection The node is well-formed. The node is not well-formed. If no parent node is found.
ProcessingInstruction The node is well-formed. The node is not well-formed. If no parent node is found.
Comment The node is well-formed. The node is not well-formed. If no parent node is found.
EntityReference Entity is declared. Entity is not declared. Not applicable.
Entity Implementation-specific. Implementation-specific. Implementation-specific.
Notation Implementation-specific. Implementation-specific. Implementation-specific.
DocumentType Implementation-specific. Implementation-specific. Implementation-specific.
DocumentFragment Not applicable. Not applicable. Not applicable.

A.2 Other validation operations

The table below describes validation outcomes from can* validation operations, such as NodeEditVAL.canRemoveChild(), or ElementEditVAL.canSetAttributeNS, CharacterDataEditVAL.canAppendData(). All these operations attempt to validate with validityType NodeEditVAL.VAL_INCOMPLETE.

VAL_TRUE VAL_FALSE VAL_UNKNOWN
If the associated operation is performed, then the node would be valid with regards to the VAL_INCOMPLETE definition or if there is no schema found. If the associated operation is performed, then the node would be invalid with regards to the VAL_INCOMPLETE definition. Not applicable.

Note: If the document includes more than one type of schema, e.g., DTD and XML Schema, and the DOMConfiguration "schema-type" parameter is not specified, the validation outcome for NodeEditVAL.VAL_INCOMPLETE and NodeEditVAL.VAL_SCHEMA is implementation-specific.

E.1 Production Systems

This specification was written in XML. The HTML, OMG IDL, Java and ECMAScript bindings were all produced automatically.

Thanks to Joe English, author of cost, which was used as the basis for producing DOM Level 1. Thanks also to Gavin Nicol, who wrote the scripts which run on top of cost. Arnaud Le Hors and Philippe Le Hégaret maintained the scripts.

After DOM Level 1, we used Xerces as the basis DOM implementation and wish to thank the authors. Philippe Le Hégaret and Arnaud Le Hors wrote the Java programs which are the DOM application.

Thanks also to Jan Kärrman, author of html2ps, which we use in creating the PostScript version of the specification.

Several of the following term definitions have been borrowed or modified from similar definitions in other W3C or standards documents. See the links within the definitions for more information.

global declaration
A global declaration is a schema declaration, usually for an element or an attribute, that is available for use in content models throughout the schema, i.e. a declaration that is not bound to a particular context.
namespace well-formed
A node is a namespace well-formed XML node if it is a well-formed node, and follow the productions and namespace constraints. If [XML 1.0] is used, the constraints are defined in [XML Namespaces]. If [XML 1.1] is used, the constraints are defined in [XML Namespaces 1.1].
schema
A schema defines a set of structural and value constraints applicable to XML documents. Schemas can be expressed in schema languages, such as DTD, XML Schema, etc.
well-formed
A node is a well-formed XML node if its serialized form, without doing any transformation during its serialization, matches its respective production in [XML 1.0] or [XML 1.1] (depending on the XML version in use) with all well-formedness constraints related to that production, and if the entities which are referenced within the node are also well-formed. If namespaces for XML are in use, the node must also be namespace well-formed.
