XML is not the problem, but schemas are too verbose to be funny. Have
you tried     $wsdl->operation(...)->explain

XML does not only define types but also element order. With type extensions,
the additional elements should be added after the elements defined in the
base-type, but in your case it seems reversed.

I have tried to find the rule back in the schema spec at
   http://www.w3.org/TR/xmlschema11-1
but it is unreadable to me. Maybe you can find the rule back.

When I look at the response message, it seems that the authors of the
schema do not understand that there is a difference between implicit
and explicit "undef". It makes me sad:
> xsi:nil="true" /><assetFactoryContainer xsi:nil="true"
> /><connectorContainer xsi:nil="true" /><contentType xsi:nil="true"
> /><contentTypeContainer xsi:nil="true" /><dataDefinition xsi:nil="true"
> /><dataDefinitionContainer xsi:nil="true" /><databaseTransport

If you use a blunt, non-schema aware XML parser (maybe your python
attempt works that way) it will, of course, produce results.

With XML::Compile you could put a hook which invokes which use
XML::LibXML::Simple or XML::Simple to parse trees which are
non-conforming. See XML::Compile::Translate::Reader section "hooks
executed as replacement" for an example (use $wsdl->addHook)  Probably
all messages will have the same problem, so need to be tricked.
