True, with the minor exception that a document that uses
owl:nameNotInTheSpec, it's still an RDF Schema
but fails to be an OWL Full ontology.

True.

One more nit: the spec formally defines the terms 'OWL DL document'
and 'OWL Full document', not 'OWL DL ontology'
nor 'OWL Full ontology'.

Hmm.. though we do seem to use 'OWL DL ontology' informally
in the overview.
