Another requested addition that I don't believe has been fully 
addressed.  If this exists in the current list, I must have missed it -- 
my apologies.

WSDL 1.1 defines services and operations and their bindings to various 
protocols.  However, the details of how an operation is identified 
(either generally or specifically in particular bindings) is, shall we 
say, rather vague.  As a result, some implementations use the namespace 
& element of the first child of Body (in SOAP RPC), others use 
SOAPAction header (in SOAP over Http), others use only the namespace, 
others the element name, others attempt to match the message type, etc. 
 As a result, interoperability suffers.

It seems like a normative model (at least) for operation determination 
is necessary for interoperability between clients and servers from 
different vendors.  This may be a requirement to define such a 
requirement for all defined bindings, as opposed to something that can 
be completely spec'd in the description.  But I believe that such a 
requirement exists.
