Jos, I'm trying to distinguish the pages in which classes and 
properties are "defined" from the ones in which they are "used" -- 
some pages do both, but in practice we are seeing a strong tendency 
to separate these - Jeff points out that the extra triple you mention 
is a strong heuristic in telling one from the other -- and the great 
majority of current DAML ontologies do indeed use the ontology 
statement -- I expect same will be true in owl...
