It is for Microsoft docuementation web service. This wsdl contains a schema that imports other schemas, but other than that it is ordinary.
I have tried using both an apache and .net scenario, but neither can create a client from this wsdl file. If I use the .NET wsdl.exe utility it can properly read the wsdl file and create a client.
I think stylus is having problems finding the imported schemas. Could you try using this wsdl file see if you get the same results and can clear up the issue for me.
