Ouch!  I was using entity above in a non-RFC2396 sense.  A simpler approach 
is to not try and define "stand for" and see if its use in the definition 
of 'reification' can "stand" unsupported:

I think that's close enough;  maybe we should focus on the offered 
definition of 'stating';  with the additional comment, I was trying to 
offer clarification but clearly achieved the opposite.
