Webservice adds XML node to xsd!?

I have a xsd and a wsdl File. Out of these two i generated a dll for
the WebClient and a dll for the WebService. So far so good.
When i trace the message the client generates, the soap-xml is correct
according to the wsdl and the xsd Files.
When is start the WebService, one welcome screen appears in IE,
telling me which functions are available and which XML is required to
talk with them.
And this XML has an EXTRA node just under my, in the XSD defined, root
node. I have no idea where this node comes from.
So when i start the client the XML is valid, but my DEBUG info on the
WebService side tells me, that it is not!!!
What the hell is going on???
Something with Document/Literal Style???

Please help,
Michael

re: Webservice adds XML node to xsd!?

hold....
partially i fixed it.
I now have the defined xml transferred and my service looks out for this xml.
Thanks
