I am not comfortable with the current model for the [action] property on response messages that requires that the [action] be specfied and the WSDL binding requires that this be set to the WSDL output binding for the input request.

I believe that the [action] element should be associated with the receiving party and not the sending party.  In the case of a response, the receiving party is the client (who's WSDL is *not* specifed on the host side).

I would like to propose that the WG consider allowing the Action property for responses to be specfied in the ReplyTo EPR so that a client can define the Action property for responses (and therefore direct the response to the appropriate dispatcher).    If not specified, the WSDL bindings as they are currently written would be used.
