By now IMHO we the WG have made the progress that D&D ought to be
in the def.  (Have we not?  I don't want to be presumptuous here.)
So the issue to be settled is whether D&D is already accounted for
in URI.

In my view URI is for addressability.  A globally unique ID offers
no intrinsic value to a resource's discovery.  E.g. there's no way
johny, seeking to buy books, can discover a book seller by
inferring from a URI like http://www.amazon.com.
Mark's made some good points; yet I find the "D&D-accounted-for-in-URI"
argument too tenuous.  Withi the web context, D&D is an integral
(as Sandeep put it) part of WS.  It's not a property that can be
assumed by default, thus calling it out is warranted.

Cheers,
