title: wsdl.exe Error: Unable to import binding '...' from namespace '...'
body: <p>When running wsdl.exe on a WSDL I created, I get this error:</p>
  <blockquote>
  <p>Error: Unable to import binding 'SomeBinding' from namespace 'SomeNS'.</p>
  <ul>
  <li>Unable to import operation 'someOperation'.</li>
  <li>These members may not be derived.</li>
  </ul>
  </blockquote>
  <p>I'm using the document-literal style, and to the best of my knowledge I'm following all the rules.</p>
  <p>To sum it up, I have a valid WSDL, but the tool doesn't like it.</p>
  <p>What I'm looking for is if someone has lots of experience with the wsdl.exe tool and knows about some secret gotcha that I don't.</p>
