That's right, but Peter's talking about using that URI to denote an 
individual not a concept ... ie. the individual which does (or doesn't 
;-) fall under the concept "The 43rd President of the US".

Which, I guess, is a good illustration of another kind of ambiguity that 
URIs are prone to ... does http://www.whitehouse.gov/#43 denote the 
concept or the individual? Does http://new.example/todays-news denote 
todays news (whatever day today happens to be) or a particular news
