This seems to be a doc definition issue. Things are defined such that the system thinks the SOAP body has one top-level element named Create_Case and then THAT document has one element named Create_Case. And the nested element doesn’t have a namespace assigned.
Can you share your document types? Or resulting WSDL? Given that Wizdler also is seeing the “extra” level, it seems the doc type definitions are going one level too deep that erroneously repeats the Create_Case doc.
