Proposed reply for O rdf:type owl:Ontology optional?

A while ago Bijan made a comment on ontology type triples.  I believe that
this comment has been addressed by one of yesterday's WG decisions.

I thus propose the following reply:

Thank you for your comment.  As it was received outside of the Last Call
review period it has not received the prompt attention it should have.

On 18 September 2003 the WebOnt Working Group decided (see to
make the O rdf:type owl:Ontology optional for anonymous ontologies.
Changes to this effect have been made in the editor's draft of OWL S&AS,
available at

Please reply to indicating whether you think
this is a satisfactory response to your commment.
