WS-Trust WSDL and WS-I BP?

["Dana Kaufman" <dkaufman@forumsys.com>]

The WS-Trust WSDL and that it seemed to violate the WS-I BP 1.0 profile.  The WSDL is of type Doc/Literal but reuses input and output messages.  When using Doc/Literal the wire signature of the messages should be unique.

5.6.7 Wire Signatures for Operations

An endpoint that supports multiple operations must unambiguously identify the operation being invoked based on the input message that it receives. This is only possible if all the operations specified in the wsdl:binding associated with an endpoint have a unique wire signature.

R2710 The operations in a wsdl:binding in a DESCRIPTION MUST result in wire signatures that are different from one another.

The Profile defines the "wire signature" of an operation in a wsdl:binding to be the fully qualified name of the child element of the soap:Body of the SOAP input message it describes. For the case of an empty soap:Body this name is an empty string.

In the case of rpc-literal binding, the operation name is used as a wrapper for the part accessors. In the document-literal case, since a wrapper with the operation name is not present, the message signatures must be correctly designed so that they meet this requirement.
