        If this were true, so would I (I don't even *like* apomorphy-based

        I guess I am just not up on my "legalese." I thought this read: "you
SHOULD use an apomorphy-based definition, but you don't have to." That, of
course, being why I proposed it as a recommendation, not a rule. I suppose,
in retrospect, that the word "new" probably belongs in there somewhere

Compare the text:

        I'm sorry if I seem sharp on this. I don't wish to pick nits, but it
was truly not my intention to suggest that they all MUST have
apomorphy-based definitions, just that they "should," to satisfy the purist
in all of us.

        Again, I hope this response does not offend!
