Darrell,

I'm afraid you've lost me entirely (which may be as much
my lack of understanding of formal languages as anything else), but I'm
afraid I'm not sure what your point is in analyzing
SGML in this way.  I have a feeling there's some valuable
insight at work, either relative to SGML itself or
data modeling in general, but I haven't a clue as to what it
might be.

I'm really confused by the question "could markup be eliminated?".
Maybe I'm being dense (wouldn't be the first time), but I fail
to see the point in this question.  It would sort of be like
asking highway engineers if roads could be eliminated because
airplanes are so much more efficient methods of transportation.
The question falls outside the parameters of the current problem,
and thus is meaningless, at least to highway engineers.
The whole value of markup is that it provides information about
the data that is not intrinsic in the data itself.  Ipso facto,
it can't be eliminated.

Perhaps it would be helpful to explain for non-scientists like
myself the meaningful difference between context free and
recursively enumerable?
