[CPN] proposal to eliminate apomorphy-based definitions

[de Queiroz, Kevin]

I think it is counter-productive to discuss eliminating apomorphy-based definitions at this stage.  This issue was considered and rejected during the process of developing the PhyloCode.  If I remember correctly, the species issue is in a different category than other previously discussed issues in that people who wished to eliminate considerations about species from the PhyloCode were encouraged to develop a proposal (at the Paris meeting).  Other proposals that have been rejected should not be up for continuous debate, or we will never make any progress.

Kevin, would you mind delaying consideration of your proposal until after we finish with the species proposal?  I'm afraid that it will get rather confusing if the CPN tries to discuss two complex issues simultaneously.
