There is already a bit in rdfs.html about localization.  I made an anchor
and linked the example back to that.

There are very many things of this variety.  The general principles are
given in AS&S.  I believe that AS&S is not the place to enumerate these
things, and, specifically, it is not the place to mention just a few of
them.   If this belongs anywhere, it belongs in Guide.

Annotation is a bit of the abstract syntax that can be used for the
ontology annotations, etc., that were recently added to OWL.  They are
fully handled in AS&S.  A detailed treatment of this subject is contained
in Section 4.2.

It should be

John rdf:type _:y .

Thanks for noticing.  I've made the fix.
