I should make clear that I agree with Pat that this concept is probably 
not useful in the ontology.  It just has to be in the list of terms and 
definitions so that we don't confuse it with any useful concept, and 
don't get accused of ignoring it.  We want to make and document the 
decision to include it or exclude it.    (01)

And I aver that it is definitely an important concept to the VIM, but 
that is because much of the VIM is about making measurements of the 
'tropes' -- measuring individuals and characterizing the individual results.    (02)
