I agree that the current hard coded URI for the soap envelope namespace needs to be 
addressed.  It seems to be a difference between soap 1.1 and soap 1.2.

soap 1.1 defines: http://schemas.xmlsoap.org/soap/envelope/
soap 1.2 defines: http://www.w3.org/2003/05/soap-envelope

Chris:
I like your approach (and patch) of determining the soap envelope namespace from the wsdl. 
  But your patch relies on the soap envelope namespace being mapped to a prefix in the 
WSDL and that it is mapped to the prefix "SOAP-ENV".  Neither are reliable.  But, as I 
said, I like the approach and I'm looking through the specs to find a way to determine the 
soap version by examining the wsdl.  Once determined, I can set the proper namespaces in 
the wsdl.Definitions objects to be used when generating the messages.
