Guarino & Welty's "OntoClean" has the same 
principle, expressed differently (they use modal 
necessity-talk rather than role-talk, and speak 
of 'rigid properties', ie non-role properties). 
It sure seems to make sense.    (06)

I recall discussing exactly this with Nicola while in Padova (some time ago)
and, to me at least, it did not seem to be sufficiently expressive.    (08)
