[tei-council] description of <constraint>

[David Sewell]

I think c) makes sense as a first step.

I also think that with the introduction of contstraint/constraintGrp we
are entering new territory where we have to expect that it may be
necessary to redesign in the future in a way that is not totally
backwards compatible. Of course that is to be avoided if possible, but
as the population of TEI users who will be making use of the new
elements is (1) relatively small and (2) relatively sophisticated,
therefore capable of making adjustments, backwards compatibility is
probably less critical here than in areas of the Guidelines that are
used by a larger population.
