I agree with this schedule - I think it's achievable if we stick to
elements and attributes. I think we should avoid getting into complex
discussions of other possibilities at this stage.

Note that if we get a representation, then it may very well act as a
catalyst to add 'DTD' information to SAX - we shall have agreed what the
most important aspects are and we shall have kept them simple :-)

P.

BTW. I see a DTD as having a tree structure because I do not treat the
element in the contentSpec as equivalent to the element declaration. IOW with:

<!ELEMENT A (B, C)>
<!ELEMENT B (#PCDATA)>
<!ELEMENT C (#PCDATA)>

I see A's tree ending with the references to B and C. If we need to find
out what they are we link to B and C rather than including them in the
tree. In that way we don't recurse.
