I have been uneasy about this for some time.
I don't think I can accept it.

I don't think rdf:datatype is a good idea at all.
It's not baked. Witness the recent interactions
with parseType="Collection".
I don't think we should use it.

I think OWL should use numerals, not numbers,
for cardinality constraints etc. That't the way
my code has been doing it for a year or so now,
and it works fine. Yes, "010" and "10" are
different numerals. So don't write "010".
