Agreed.  The translation rule for individualvaluedPropertyID should be
changed to make its first triple be optional if there is a triple in the
translation of the ontology that give the ID one of the three
more-specific OWL property types.

Again, this should be agreed on by the WG.

I believe that OWLP already acts in this modified manner.
