That does NOT address my concern, for two reasons: (a) it
is missing the word "should" or similar; and (b) the word
"identify" is specifically defined in the RDF Semantics
to be a different notion from "denote", but the definition
is so vague the term is essentially meaningless:

   "IRI meanings may also be determined by other constraints
   external to the RDF semantics; when we wish to refer to such
   an externally defined naming relationship, we will use the
   word *identify* and its cognates."
