2.8 Binding Operations

Description[top]

For every Interface Operation component contained in an Interface component, in addition to the default binding rules described in [Default Binding Rules], there may be additional binding information to be specified. This binding specification allows the user to indicate the SOAP Message Exchange Pattern (MEP) and a value for the SOAP Action Feature (see [SOAP12-PART2]) on a per-operation basis.

Relationship to WSDL Component Model[top]

The SOAP Operation binding specification adds the following property to the WSDL component model (as defined in [WSDL-PART1]):

• {soap mep}, an absolute URI as defined by [RFC2396], to the Binding Operation component. The value of this property identifies the SOAP Message Exchange Pattern (MEP) (as defined by [SOAP12-PART1]) for this specific operation. If no specific value is assigned, then the value assigned by the default rules apply (see [Default Binding Rules]). It is an error for this property to not have a value (which MAY happen if the default rules are not applicable).

• {soap action}, an absolute URI as defined by [RFC2396], to the Binding Operation component. The value of this property identifies the value of the SOAP Action Feature (as defined by [SOAP12-PART1]) for this specific operation.

XML Representation[top]

<definitions >
  <binding >
    <operation ref="xs:QName" 
               wsoap:mep="xs:anyURI"?
               wsoap:action="xs:anyURI"? >
    </operation>
  </binding>
</definitions>

The XML representation for binding an Operation are two attribute information items with the following Infoset properties:

• wsoap:mep OPTIONAL attribute information item

  • A [local name] of mep

  • A [namespace name] of http://www.w3.org/2004/08/wsdl/soap12

• wsoap:action OPTIONAL attribute information item

  • A [local name] of action

  • A [namespace name] of http://www.w3.org/2004/08/wsdl/soap12
