I think Umit was intending to talk about the WSDL 2.0 *spec* requiring it 
of WSDs -- not the WSD *author* requiring it of a particular service.

The question is:  When a service requires its users to support a particular 
mechanism for determining the wsdl:operation name in order to use that 
service, should the WSD author be required to indicate that mechanism as 
wsdl:required in the WSD?  Some think the WSDL 2.0 spec should make this 
requirement in order to prevent the interop issue illustrated by Scenario 
X[1]; some don't.

1. Scenario X:
