Re: AS & S review

Passing the buck...

As I recall, we identified good ol' REF as the "dustbin" document.  At 
this point we are not accepting major changes to Guide.  So "lists of 
lists" restrictions should go in REF, if anywhere...

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.
