As a botanist, I don't know vertebrate taxonomy and nomenclature well
enough to answer this question (and I have to confess that I haven't
tried to follow the details of the recent discussion between Mike
Keesey and David Marjanovic about alternative names for various
vertebrate clades).  There are other subscribers to this listserv who
are familiar with both the PhyloCode and vertebrate taxonomy and who
would therefore be in a better position to answer Mike's question.
