Do you think this is part of the "contract" between the client and server 
provider ?  I mean the client has to learn about these before they can 
properly make their invocation request.  If WSDL "Bindings" is to provide 
the mapping from an abstract operation to what needs to go into the wire, 
then it seems to a good place to cover this.  Or, where else (in any WS??) 
have we covered it ?

Best regards,
