> I'm building a proxy service that executes an XSLT mediation where there is no one-to-one mapping between the operations defined by the proxy and the operations invoked on the target. Actually the proxy defines several operations that all execute the same operation on the target (with different input). Therefore the XSL transformation for the response requires knowledge about the original request, namely the operation invoked. While it is possible to do this based on the name of the element in the SOAP body of the original request, it would be easier if the mediation had access to the name of the operation invoked on the proxy. Axis easily gives access to this information through MessageContext#getAxisOperation. The information is available if the proxy service has a publishWSDL element. As far as I can see, Synapse doesn't expose this information to the mediation.
> I propose to modify the get-property function to expose this information in a similar way to what is done e.g. for the WSA-Action. Since the operation is identified by a QName and this type is not supported by Jaxen, actually two new properties would be introduced: 'OperationName' and 'OperationNamespace'. Only modification of GetPropertyFunction and SynapseConstants (to define the property names) is required to implement this.
> Attached is a proposed patch implementing this change.
