My mind is still open to learn about the Web ...
There are URI's and there are RESOURCE's.
A URI is an identification of a RESOURCE in a universal space
(called URI-space).
Of course we have to use a notation for that!
If we use mathematical notation:
  u for URI
  r for RESOURCE
  It is an axiom that: u1 = u2 => r1 = r2 (just accept that)
If we use machine notation:
  URI-reference representation for URI
  literal-or-xml representation for RESOURCE
  A RESOURCE can have multiple (0, 1 or more) such representations

have to think now about anonymous RESOURCE's, proof-value RESOURCE's ...
