Minor points - nothing for LC:

>> [*] "*MUST* ....and the words appear as emphasized text, "
>> The document does not use them in this way. They are not in bold later, and
>> bold is reserved for HTTP Verbs.
>> SmallCaps might be useful to emphasize.
> I switched to italics rather than bold.

What's the intention for the rest of the document?  These words are not 
used italized.  I was expecting the RFC 2119 text to be in the same 
style as used in the document as a whole: capitals would be the easiest way.

A compliant implementation of this specification SHOULD accept HTTP 
requests directed at its Graph Store
has SHOULD in plain upper case.

(not necessary for LC)

Fine - if there is to be a defintion, make like your example, which is 
not a verb.

"An RDF Document is
a serialization of an RDF Graph into a concrete syntax."

Yes - it's a WG-wide matter.

Excellent - I think it works well this way.
