If you re-read the full question, Derek also asked:
>> Does the ICZN forbid or recommend against this?
THAT is what Thomas and I were replying to. "A diagnostic feature"
(which geography may certainly be) is not necessarily synonymous with
"a Code-compliant descriptor", and - in my opinion - the Code does
effectively forbid it, in the sense that geography *alone* cannot be
used to define a taxon.
