Yes, however will that metadata be about *resources* as with RDF, or about
*representations* as with HTML <meta> tags and ALT attributes and embedded
JPEG/PNG metadata and so on?

Sorry, I did not say that clearly. I meant that URI+fragID is no longer a
URI, it is a new syntactic construct (URI ref) which acts as a shorthand
for a URI plus some additional locator that operates on representations.

Using this construct to denote something other than a fragment of a
representation available at a particular URI seems harmful, and is
certainly underspecified.
