Consistency of character lists across taxon could be handled by the document
type definition for that taxon class (or some other mechanism if we do not use
XML in the end) for a collection of taxon descriptions. The dtd defines what
can go into the treatments and how they may be combined.

Yes, perhaps there are really two different fields
Treatment creation time and revision number. I think time alone is not enough
since one can not tell from that if the treatment has changed since it was
viewed or used (to create higher level treatments).

It could
