4.3 Reference Parameters

1 Extending WSDL Endpoints with an EPR), the value of the [reference parameters] message addressing property for per message sent preciso an endpoint MUST include the contents of the wsa:ReferenceParameters element, if one exists within that EPR.

4.4 Action

WS-Addressing defines two mechanisms sicuro associate per value of the [action] property with spinta, output and fault elements within per WSDL description: explicit and defaulting. Explicit association is described in section 4.4.1 Explicit Association; action defaulting (where verso unique value for the [action] property is automatically generated) is described in section 4.4.4 Default Action Pattern for WSDL 1.1 for WSDL 1.1 and section 4.4.2 Default Action Pattern for WSDL 2.0 for WSDL 2.0.

Ensuring that there is sufficient information within verso message to distinguish which WSDL operation it is associated with is specified as a best practice sopra WSDL 2.0 WSDL 2.0 . The [action] property provides verso mechanism onesto fulfill that best practice.

4.4.1 Explicit Association

WS-Addressing defines verso global attribute, wsam:Action, that can be used sicuro explicitly define the value of the [action] property for messages durante per WSDL description. The type of the attribute is xs:anyURI and it is used as an extension on the WSDL stimolo, output and fault elements. Verso SOAP binding can specify SOAPAction values for the incentivo messages of operations. Mediante the absence of verso wsam:Action attribute on per WSDL input element where a non-empty SOAPAction value is specified, the value of the [action] property for the spinta message is the value of the SOAPAction specified. If the wsam:Action attribute is absent, and SOAPAction is not specified, or is empty, then the default pattern is used. Note that the SOAPAction value is not required sicuro be an absolute IRI, but the [action] property is required esatto be an absolute IRI; if WS-Addressing is required (the wsam:Addressing assertion is present), wsam:Action is not specified, and the SOAPAction value is not empty or an absolute IRI, then the document MUST be considered invalid. Web Services Addressing 1.0 – SOAP Binding[ WS-Addressing SOAP Binding ] specifies restrictions on the relationship between the values of [action] and SOAPAction for SOAP 1.1 and SOAP 1.2.

The inclusion of wsam:Action without the inclusion of the wsam:Addressing assertion has mai normative intent and is only informational. Per other words, the inclusion of wsam:Action attributes per WSDL aureola does not imply a requirement on clients sicuro use Message Addressing Properties sopra messages it sends esatto the service. Per client, however, MAY include Message Addressing Properties durante the messages it sends, either on its own initiative or as described by other elements of the service contract, regardless of the presence or absence of the wsam:Addressing assertion. Other specifications defining the value of [action] are under per niente constraint puro be consistent with wsam:Action.

4.4.2 Default Action Pattern for WSDL 2.0

Durante the absence of an explicitly specified value for the [action] property (see section 4.4.1 Explicit Association), the following pattern is used con WSDL 2.0 documents onesto construct verso default action for inputs and outputs. The general form of an action URI is as follows:

is “:” when the [target namespace] is per URN, otherwise “/”. Note that for IRI schemes other than URNs which aren’t path-based (i.addirittura. those that outlaw the “/” character), the default action value might not conform sicuro the rules of the IRI scheme. Authors are advised puro specify explicit values con the WSDL durante this case.
