4.3 Reference Parameters
1 Extending WSDL Endpoints with an EPR), the value of the [reference parameters] message addressing property for per message sent onesto 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 preciso associate verso value of the [action] property with input, output and fault elements within verso WSDL description: explicit and defaulting. Explicit association is described durante 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 per message onesto distinguish which WSDL operation it is associated with is specified as verso best practice in WSDL 2.0 WSDL 2.0 . The [action] property provides per mechanism esatto fulfill that best practice.
4.4.1 Explicit Association
WS-Addressing defines a global attribute, wsam:Action, that can be used onesto explicitly define the value of the [action] property for messages sopra verso WSDL description. The type of the attribute is xs:anyURI and it is used as suggerimenti polish hearts an extension on the WSDL stimolo, output and fault elements. Per SOAP binding can specify SOAPAction values for the spinta messages of operations. Per the absence of verso wsam:Action attribute on a WSDL molla element where verso 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 puro 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 giammai normative intent and is only informational. Sopra other words, the inclusion of wsam:Action attributes per WSDL aureola does not imply verso requirement on clients esatto use Message Addressing Properties in messages it sends preciso the service. Verso client, however, MAY include Message Addressing Properties per 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 in nessun caso constraint puro be consistent with wsam:Action.

4.4.2 Default Action Pattern for WSDL 2.0
Per the absence of an explicitly specified value for the [action] property (see section 4.4.1 Explicit Association), the following pattern is used sopra WSDL 2.0 documents sicuro construct a default action for inputs and outputs. The general form of an action URI is as follows:
is “:” when the [target namespace] is verso URN, otherwise “/”. Note that for IRI schemes other than URNs which aren’t path-based (i.ancora. those that outlaw the “/” character), the default action value might not conform to the rules of the IRI scheme. Authors are advised sicuro specify explicit values per the WSDL mediante this case.
