Personally, I think & should be limited to just 'leaf' nodes only. This
would keep it sane, and allow it to be implemented as a special case
content model (as we already do for Mixed anyway.) This would provide a lot
of usefulness without forcing everyone to throw out the very fast and
compact DFA type representations in wide use now, or implement another
(much more complex one) in addition to.

People should accept the fact that XML is not going to solve all problems
and still stay light enough to remain what it was intended to be. Schema
will already be very bloated with all the other stuff in it now. I
guesstimate that a Schema implementation will probably be at least twice
the size of the existing parser code in most implementations, if not more
so. Anyone think differently?
