This specification uses a number of namespace prefixes throughout; they are listed in . Note that the choice of any namespace prefix is arbitrary and not semantically significant (see ).

This specification uses curly brackets (e.g., {property}) to indicate a property in the WSDL component model, as defined in Part 1 Component Model.

Namespace names of the general form http://example.org/... and http://example.com/... represent application or context-dependent URIs .

All parts of this specification are normative, with the EXCEPTION of examples, and sections explicitly marked as "Non-Normative".

A SOAP Binding is identified as a SOAP 1.1 binding by assigning the value 1.1 to the soap version property of the Binding component.

The SOAP 1.1 binding enables Web Service applications to use SOAP 1.1 by extending the SOAP binding in the WSDL Adjuncts specification . This binding supports the following:

The values of soap mep default, soap mep and soap fault subcodes properties are ignored for SOAP 1.1 binding.

Default Binding Rule

The following default binding rule applies to SOAP 1.1 binding:

SOAP Action. If the Binding Operation component does NOT have a soap action property defined, then the quoted empty string value ("") value is used for the SOAP 1.1 SOAPAction HTTP Header Field (see ).

The following example shows the WSDL definition of a simple service providing stock quotes. This service supports a single operation called GetLastTradePrice, which is deployed using the SOAP 1.1 protocol over HTTP. GetLastTradePrice operation request takes a ticker symbol of type string, and returns the price as a float.
