I don't understand this. Why wouldn't I just use
    http://danbri.org/foo.html#danbri
or anything similar for HTML fragments? (I'm assuming that foaf.rdf 
returns an application/rdf+xml documend, and foo.html returns an 
application/xhtml+xml document; the extensions may be meaningless to the 
protocol but help to keep things apart for humans and computers.)

Also, I don't see much of a need to denote an RDF node per se. I'm sure 
there are special applications one can come up with where reasoning 
about RDF nodes per se is helpful/necessary/whatever, but for such 
cases, there are other techniques available already. A single special 
property and blank nodes would do the job.
