In addition, I wonder how the PhyloCode establishes priority?  Suppose two
different labs have developed competing phylogenies for the same group of
taxa.  Each lab publishes a well-supported phylogeny based on the data
they have used (could be morphological vs. cpDNA, cpDNA vs. mtDNA, mtDNA
vs. nDNA, etc.) and each publishes a series of clade names to reflect
their understanding of relationships among these taxa.  How does one
decide which classification is considered "correct"?  Or, is each
classification viewed as a working hypothesis and all the names are given
some sort of temporary status?  Maybe there is a way to construct a
consensus of the two classifications and choose clade names based on which
clades (if any) from each classification are preserved.
