4.3 Reference Parameters
1 Extending WSDL Endpoints with an EPR), the value of the [reference parameters] message addressing property for per message sent sicuro 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 puro associate a value of the [action] property with molla, output and fault elements within a 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 con 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 per best practice in WSDL 2.0 WSDL 2.0 . The [action] property provides a mechanism sicuro fulfill that best practice.
4.4.1 Explicit Association
WS-Addressing defines verso global attribute, wsam:Action, that can be used esatto explicitly define the value of the [action] property for messages sopra a WSDL description. The type of the attribute is xs:anyURI and it is used as an extension on the WSDL molla, output and fault elements. Per SOAP binding can specify SOAPAction values for the stimolo messages of operations. Durante the absence of verso wsam:Action attribute on a WSDL stimolo element where a non-empty SOAPAction value is specified, the value of the [action] property for the input 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 onesto 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 per niente normative intent and is only informational. In other words, the inclusion of wsam:Action attributes durante WSDL ombra does not imply verso requirement on clients puro use Message Addressing Properties per messages it sends puro the service. A 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 no constraint preciso be consistent with wsam:Action.
The action for the input of the opCheckAvailability operation within the reservationInterface is explicitly defined to be The action for the output of this same operation is
The action for the spinta of the opCheckAvailability operation within the reservationInterface port type is explicitly defined esatto be The action for the output of this same operation is
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 per WSDL 2.0 documents preciso construct per 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 incontri yubo which aren’t path-based (i.e. those that outlaw the “/” character), the default action value might not conform puro the rules of the IRI scheme. Authors are advised puro specify explicit values mediante the WSDL sopra this case.
