Just to be quite clear, I was most certainly *not* expressing misgivings
about the suitability of CycL for general-purpose KRL.   I concur that it
is quite suitable for such purposes.   I was suggesting:
	a) that it may not be part of the SUO group's mandate to choose a KRL.  
	b) even if it is part of of the SUO group's focus, the question of
adopting OpenCyc as a SUO candidate is usefully distinguished from the
question of adopting CycL as a standard KRL.  Such a request is completely
consistent with believing that both, one or neither are perfectly wonderful
wrt to their respective selection criteria.
