comment on O

http://www.w3.org/TR/2003/CR-owl-semantics-20030818/mapping.html#4.1

The second rule seems to *require* that every ontology includes a triple 

xxx rdf:type owl:Ontology .

where xxx is either the name of the ontology or a blank node.

This does not appear to be the intent elsewhere.
The triple
O rdf:type owl:Ontology .

could be included in the Annotation rules instead.
