Hi Amit -

Please allow me to add the following to my previous message - You are 
right of course that we should focus on meeting the needs of the vendor 
and user community, and avoid counterproductive feuding, and I 
appreciate that you have emphasized this point of view.  I agree that we 
should take attribution issues offline, and I also agree with your 
emphasis on collaboration and on building useful tools.  My main point 
in recent messages has been that we could and should work together in 
this regard.  In fact, I think (something like) WSDL-S together with 
(something like) OWL-S (lite) could provide a very nice bridge between 
the Web service and Semantic Web efforts at W3C.  (And this is not to 
suggest that this would be the only path towards adding semantics to Web
