title: Multiple wsdl and xsd files... into a single wsdl
body: <p>Probably is a straight-forward question: do you know any tools for combining multiple wsdl + xsd files into a single wsdl? </p>
  
  <p>Thank you.</p>
  
  <p><strong>Edit1:</strong>
  The service is a WCF service, and I want to have a single wsdl for PHP (as client).</p>
  
  <p><strong>Edit2:</strong>
  Too bad I need to use .Net 4.0 and not 4.5 where this would be possible. Maybe I could borrow then one of the new MS tools? Do you know which one? Is the svcutil.exe the responsible tool? If yes, what are his dependencies? Because I don't want to jump to .Net 4.5 just yet.</p>
