Hi iffi,
This form of WSDL / XSD / WS-Policy (not in WSE yet, BUT it is in Indigo)
exchange is know as WS-MetadataExchange or MEX for short.
This sort of using standard SOAP API Packets as querying mechanisms is used
widely by UDDI deployments. Think of MEX as something rather similar.
WSE 2.0 supports some kind of MEX exchange thru something you have just
described. Could you post the "serialized" SOAP Envelope here so we are able
to inspect what is the Tcp endpoint actually receiving ?

Thank you.
