2004-02-12 Action Item: Clarification to the OperationName feature

Folks,

I was given an action item [1] to clarify the usage of OperationName 
feature [2], to clarify what is required and what must be specified in 
WSDL.

Addendum to the Proposal:

OperationName feature is a required feature for all WSDL descriptions. 
It is not specific to a binding since all bindings must implement this 
feature. Therefore, the feature is not required to be declared as shown 
below as it is assumed to be present in all descriptions:

<binding>
   ...
   <feature uri="http://www.w3.org/TR/wsdl20/features/operationName" 
required="true"/>
</binding>

Note: This syntax may change per compositor syntax proposal [3].

There may be multiple ways to implement this feature. The proposal 
specifies a distinct method for implementing this feature by using a 
soap module for SOAP bindings. When the soap module specified by [2] is 
used as the implementation method, its use must be declared in WSDL as 
follows:

<binding>
     ...
     <wsoap:module 
uri="http://www.w3.org/TR/wsdl20/OperationDispatchModule" required="true"/>
</binding>

Note: The original proposal did not specify a URI for the SOAP module 
that has been specified here.

The SOAP Action feature may also be engaged in the binding in addition 
to the OperationName feature as shown below:

<binding>
    ...
    <feature uri="http://www.w3.org/2003/05/soap/features/action/"/>
</binding>

In this case, the OperationName feature also specifies the value of the 
SOAP Action property as discussed in [2].
