If a minimal requirement for Large OWL is not defined, we can have
an implementation of Large OWL that is solely given with the Classes
as instances feature.  I am cuorious if this implementation is usable
or not for those who want to have the Classes as instances feature in
the OWL Lite.


Another point is if a minimal requirement for Large OWL is not defined,
the Large OWL is not a language but a class of ontology languages.
This means we might have a complecated "network" of languages within
the Large OWL(s).  However, I still strongly support to have the inclusion
ordering: OWL Lite < OWL/FOL < Large OWL, because it makes easier
for ontology users to decide which OWL should be used for individual
situations.
