After you figure out how the message should look like, pass it with
the
rest of the parameters to the submitMessage.
"suds" should take care of the rest. Like wrap everything
into Envelope, send the request and parse response.

If you have to build XML from python let me point you to very useful
http://svn.effbot.python-hosting.com/stuff/sandbox/elementlib/builder.py
or
http://codespeak.net/lxml/api/lxml.builder.ElementMaker-class.html

python<->xsd thingy you mention could be "lxml" library that is an
implementation of ElementTree + "number of very useful extensions".
Most of the time XSD is used to validate XML documents.
