It's a bit tricky...and I'm not sure if we should update the  
canonical parsing process or not.

(First, I think it would be better to say "RDF/XML document"  
throughout, since a NTriples document is arguably an "RDF document".)

So, in section 2.1.1, at the end:
	An RDF/XML document may not conform to <http://www.w3.org/TR/2004/ 
REC-rdf-syntax-grammar-20040210/> only in respect to containing a  
character from a version Unicode greater than 3 and a version of XML  
greater than 1.0 second edition [[have to check]] but otherwise can  
be successfully processed. In these cases, the respective document is  
an xxx document in Unicode version# and XML version#. Without  
explicit Unicode versions, the documents default to the latest  
version of RDF...

I would say in 2.2:
""As noted above, any conformant OWL 2 tool must accept ontology  
documents using the RDF/XML serialisation [OWL 2 Mapping to RDF  
Graphs] with Unicode 3.whateveritis and XMLwhateveritis. It *may*  
also accept documents with Unicode and XML versions higher than that,  
but it must report it?!?"
Entailment doesn't change, I think.

I could imagine text saying that serializers SHOULD use the version  
specified in the latest version of the RDF spec?

I don't know, Ian, if this is enough for you to go on.

Cheers,
Bijan.
