trouble sending XML payload in SOAP::Lite -> .NET

Hi. I've been pulling my hair out here.

I'm interacting with a web service that has two methods. One takes a
simple string arg and returns an XML payload. I've got that working,
having worked through the SOAP::Lite -> .NET gotchas.

Now I'm trying to get the next method to work. In this one, the .NET
provided sample request would look like:


xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">




SCHEMA

XML





When I use the same code that worked for the first method but
substitute a schema for SCHEMA and an xml block (that conforms to
SCHEMA) for XML, I get all sorts of trouble.

If I use SOAP::Lite (+trace => debug) I see that all my xml has its '<'
characters escaped to < I've seen posts that say this is no problem
and the proper way to do things but I'm not sure. In any event I don't
know how to turn on or off this behavior. The server responds that
"Object reference not set to an instance of an object."

I've also tried SOAP::Lite::Simple::DotNet but that does strange things
to my SCHEMA namespaces no matter what the value of strip_default_xmlns
is. For example the schema line:



gets translated into



and I get a namespace error on "xs".

Can somebody shed some light on this or point me to a page that
discusses uploading XML to .Net servers from SOAP::Lite? I've found a
paucity of examples of SOAP::Lite that involve a client sending xml as
a method argument.

Thanks,

Jim
