I read that when you posted it and i was deeply confused and sad :) In 
the TMDM spec from 2005-07-13, there was the section "7.5.3 Subjects for 
defined terms". I thought that would cut it pretty well ?!? Since it is 
not in there anymore, i obviously missed something.

For two reasons:

-) If I would want to import a XTM 1.0 map into a TMDM store, it is one 
of the things that is referenced, and therefore must exist.
-) If I would be occurrence, i would ask the editors: "Why does name get 
one and i don't?" :) And the rest of the family would cheer in, in 
particular role and association.

Kind regards,
Robert
