title: Error: Validation of SOAP-Encoded messages not supported
body: <p>I'm attempting to connect to a vendor's webservice (Soap 1.1), but I get this error:</p>
  
  <p><strong>line -1: Validation of SOAP-Encoded messages not supported</strong></p>
  
  <p>The vendor's support person with whom I'm communicating is using the same tool (SoapUI v4, I've tried both v4 and v5, and we've confirmed we're using identical XML), but he has no trouble, and a Google search of the error message hasn't uncovered anything helpful. Does anyone have any thoughts what the problem could be? Perhaps a program setting?</p>
