Ah, yes, that was a painful mistake in the 1st edition of the Primer (and
in the derived chapter in the Ontology Handbook).

The new editions of the Primer contain the correct version:

"No cardinality restrictions may be placed on transitive properties (or 
their *super*properties, which are of course also transitive, by implication)."

Sorry for the confusion this has caused...

Frank.
