For item 03-000, the CCT text actually says "A character string (letters, 
figures or symbols) that for brevity and/or language independence may be 
used ..."  In terms of capturing the semantics of this item, if it can 
represent anything, then we can't say anything more about it other than 
it's a string.    (03)

The SUMO relation &%time relates something to a point on the timeline, 
which is both a date and a time.  So, I think this is correct for item 04-000.    (05)

07-002 should probably be SUMO UnitOfMeasure since it appears just to the 
unit, without the number of the units.  Do you agree?    (07)

For 09-005 I think this is correct.  SUMO &%Agent includes groups of people.    (09)

Actually, it looks like you sent this to the ontolog-forum, but that's ok I 
think.    (011)

I'm not sure what you mean by "associations of natural language and 
CCT".  SUMO is a formal, logical model, and definitely not natural 
language.  Have you clicked on the links to SUMO, in order to read the axioms?    (013)

Thanks again for the comments.    (014)
