The URL is alive and well.

The W3C "definition",
 "a URL is a type of URI that identifies a resource via a representation of 
its primary access mechanism (e.g., its network "location"), rather than by 
some other attributes it may have. Thus as we noted, "http:" is a URI 
scheme. An http URI is a URL."

SRU, for example, considers it's request to be  URL.

I do think this conversation has played itself out.   --Ray
