As an interested outsider, I prefer the wording you suggest, David.  I think 
that requiring the name attributes of WSDL elements to be unique would be 
sufficient.  I think it would be dangerous to fix on a particular system for 
ensuring this, because, unfortunately, ID attributes are in a bit of  
practical limbo these days.  Just making this a normative clause in the WSDL 
spec should do the trick.

From my POV, the important thing is to allow a clean and clear mapping from 
WSDL elements to RDF descriptions, and ensuring unique WSDL qnames would make 
things a bit smoother, ID type or no.
