I like this document.  Would suggest at least one example (or link to
example) for each construct.

Re the OWL/RDF triple relationship:

This is easy to mis-read.  An OWL knowledge base is a collection of
RDF triples as restricted by this document.  

Reading this one might assume that a collection of OWL triples honors
the RDF requirements for collections of triples.  RDF imposes
restrictions that OWL relaxs (e.g. subclassof loops, single range and
domain constraint, ...).  OWL imposes restriction that RDF does not
(e.g. list first/rest sequences terminated by NIL).

Many collections of RDF triples are not given a meaning by the OWL
semantics exactly because they do not conform to the restrictions
listed in this document.

Normally I think of vocabulary as lexical.  We are specifying the
triples that constitute the OWL language (or one representation of
