Yes.  This is *exactly* the question I've been trying to ask, but 
haven't put it as clearly as Jonathan did.  I just think that 
inferencing the range of a URI based on its scheme feels fragile and 
inflexible.  Especially since the taxonomic division between what 
Jonathan calls a web:document and other kind of things feels like just 
one of a hundred interesting assertions one might want to make about 
whatever a URI names, and for damn sure we can't infer all of them from 
the syntax. -Tim
