I am running wsdl.exe to try and generate some classes and I am getting:

wsdl ppc.wsdl

Error: Unable to import binding 'PPCBinding' from namespace

 - Schema with targetNamespace='http://tempuri.org/PPC/schemas' has invalid
syntax.

If you would like more help, please type "wsdl /?".

The error messsage does not give a line number so I am not sure what
specific syntax is causing the problem. I have read the WSDL into XML Spy and
I don't see any errors. Any ideas on what I can do to diagnose this problem?

Thank you.
