No reply on this. I was expecting this. I am actually very disappointed now.
Initially I liked WSE... the pipeline model and so ..... but whenever I tried
to use WSE for interoperability I have also failed (100% failure).

These are the questions I asked the group:
1-
http://groups-beta.google.com/group/microsoft.public.dotnet.framework.webservice
s.enhancements/browse_thread/thread/8aa64ca0753743fa/15a5e67a28c7c557?q=wsu:ID+w

2-http://groups-beta.google.com/group/microsoft.public.dotnet.framework.webservice
s.enhancements/browse_thread/thread/b5ff42201bd34e01/68cd6fecdd16c3c7?q=Httpwebr
equest+WSE&rnum=1&hl=en#68cd6fecdd16c3c7
3- This one.

and I never got any answer from WSE Team. For second question John tried to
help me but I have to use SoapClient there.

I am not saying a software has to have no flaws in design or should be bug
free... I asked if WSE team could validate my understanding at least and
promise for improvement (if any) in future release and no reply

Very disappointed.

Not going to use WSE from now onwards.

For me Webservices are there to have interoperability between .NET and Java
systems ...and if this does not work then we have a failure.
