Are we still using "identifies" when denotes appears to be much clearer 
re. this particular matter?

A URI can denote anything.
An HTTP URI can denote anything.
An HTTP URL specifically denotes a Web document.
A Resource is the Content associated with a Web document.
A Document is comprised of Content.

Linked Data demonstrates how you can use *indirection*  to denote 
*anything* using an HTTP URI. In this usage context said URI resolves to 
associated content at a Web address/location (URL). Note, *indirection* 
may be explicit (303 redirection) or implicit (via use of a fragment id 
or hash).
