Just to be clear, these three DoV refer to common ways in which the 
technology may be subdivided for conformance-specification purposes.

It is an interesting point.  "DoV" in general refers to the "ways in which 
conformant implementions can vary amongst themselves".  We have enumerated 
8 DoV (the Enumerated DoV), with some argument ongoing about GL3.  I don't 
think that we are pretending (or should pretend) that the Enumerated DoV 
exhaust the possibilities.

I recall arguing in the past, my view of GL3 as a catch-all to flush out a 
spec's conformance assumptions that do not fit into one of the other 
GL.  This would include the other 7 DoV GL.

So ... are you suggesting a CP for a generic or catch-all DoV?  Roughly, 
something like, "Describe any ways in which conformant implementations may 
vary amongst themselves, if those ways are not subsumed under one of the 
Enumerated DoV."
