Hi Guus, Alistair, Sean,

Maybe it can be useful for me to intercept the following points of Guus' 
review before a next version of the Reference is released:

> 4.6.3 named RDF graphs
> Explain (or refer to Primer) the issue of schema containment and 
> potential use of SPARQL + named graphs

There is nothing in the Primer about that! It was actually refering to 
an Annex E of the Reference, which has disappeared since...

http://www.w3.org/TR/rdf-primer/#rdfvalue discusses how to use that, and in terms that fit nicely the documentation-as-structured-object pattern, I found.
The editor's draft of the Primer to be released this week also mentions it.
Anyway, the use of the documentation-as-structured-object will be rarely used, I guess. So I'd be not that uncomfortable with using for that an RDF feature that is rare ;-)

There is (will be) an example in the Primer :
