XML-Schema is quite complex, too complex for me to tell how
the XML should look like for the type definition above.

I hope that "suds" will know how to serialize corresponding objects.

You cannot necessarily translate Java code examples literally to Python.
XML-Schema (and SOAP) is made to provide interoperability at the
XML level, not the language level.

As I wrote, "suds" usually uses a factory to create type instances.
For them, it knows how to serialize them. "suds" often allows to
pass simple Python type instances and does the right thing. But,
in your special case, it might not...

Usually, "suds" adds namespaces as directed by the WSDL.

I do not know.
I have not used "suds" with types of the kind you have shown above.


In my cases, "print obj" has shown me what attributes "obj" has
and I have assigned values to them. That was is.
I do not know how "suds" handles XML-Schema "restriction".
Maybe, you find something in the "suds" documentation?

As you can see, the parameter has not been serialized correctly.

The reason might be that "suds" does not accept a list as an
"ArrayOf_soapenc_string" (in this case, some fiddling with
a properly constructed instance might help) or that it cannot handle
this type at all (in which case, you would need to contact the author,
maybe via a bug tracker).
