Suggestion for next round of model theory document

It's a bit of a nit, I note that the document still uses the term "URI" 
when talking about RDF resource identifiers.  I think that this may cause 
confusion in the future.

As a simple fix, I would suggest placing (something like) the following 
text at the start of section 0.2 and/or 1.2:

[[[
For the purposes of this document, the term <dfn>URI</dfn> is used to mean 
an absolute URI with an optional fragment identifier.
]]]
