Holger Sunke updated CXF-7159:
------------------------------
    Attachment: schemaConflict_v2.7z

Thanks for your feedback. Seemes I have stripped off some importend stuff from 
the WSDL. Due to license I cannot provide the original WSDL + XSDs.

I added xsd:element part so that it logically looks more like the original 
structure.

> The offending Namespace http://www.w3.org/2001/XMLSchema is already added on

> -I have devleoped a standalone test case you only need to extract and run 
> "mvn test" for reproducing this. How can I upload it?-
