Yep, I agree - three things are beind identified and three URI are 
required:.

Linus Torvalda the person
  http://foo/#LinusTorvalds
a documdent that contains RDFS statements that describe facts about 
Linus Torvalds
  http://foo/
a graph that contains nodes and links that describe facts about Linus 
Torvalds
  http://foo/#ThisGraph

Note that the abstract things are identified by UriRef(s) with fragments 
and the tangeable document is identified by a URI.
