Please elaborate on the shades of gray.  I didn't get that obviously, and
apologies to Dave.

IMO, there is nothing wrong with the set approach other than it might be
insufficiently detailed and in cases where it matters, non-dynamic.  I
haven't been a subscriber to the TAG list for the last year so I've no
currency with respect to the discussions there.  For me, this is a partially
theoretical discussion in that I consider code versioning a *tools* problem
(eg, integration of CVS and Microsoft tools can be strange).  On the other
hand, the applications of dynamic systems theory to the problem interests
me.  It is a neat problem and 'tuning' solutions seem to be applicable.

I don't recognize the set formulation as being mine.  They are one of the 
approaches being tried as the TAG works toward a finding on versioning, 
but of all the TAG members I am probably among the less enthusiastic about 
the approach, in part because I don't yet see how it deals with the shades 
of gray that I outlined in my note earlier today.  I'm not hard over 
against the set approach either, just trying to see how it works out.  In 
nay case, I think it was Dave Orchard who advocated the set-based approach 
on in this xml-dev thread.
