Leonard, and all

Leonard's point goes along the same line as my previous message. Let's 
extend the notion of document to be equivalent to "resource", and we're 
done. That was all the point of the URI specification to begin with. 
Another hit on that nail : The notion of document is extended in many 
ways in various communities to anything bearing information. The first 
information on a thing being to be made distinct from the continuum of 
the universe, through naming, identifying, and asserting distinctive 
properties (such as a URI), as long as something is identified, it bears 
information, hence can be considered a document.
A bit farfetched maybe, but closing the debate, conceptually and 


PS : I vote for "A", of course.
