Tricky one, this. I can see the logic in keeping these in, especially where
entities are involved. OTOH they are the sort of information that
distinguishes simple WF docs (i.e. no internal/external subsets) from those
with subsets. [BTW we need a terminology for these various types of
documents...].  The WG has already realised the problem of ID by (I think
in XSL) treating *attributeNames* of ID as special (since it recognises
that not all authors may declare the *attributeType*).

I can live without this. But others may not be able to do so :-)

This is part of what we've been discussing, right?

Suggest that you rephrase it as questions.  e.g. Q11 "Should SAX be able to
recreate an ESIS stream?" I'd want good evidence why. [One reason could be
that in that way one can easily compare the output of parsers, and also
compare it with nsgmls and other ESIS-aware tools.]
