It's worthwhile, perhaps, to ask whether there will be many XML
applications that

a) require a small footprint;
b) need DTD information; and
c) can use the information in a streaming format.

Any kind of DTD-driven editing tool needs to store the DTD in some
kind of a persistent structure, and I imagine that most XML processing 
on small clients will not worry much about DTDs at all.

To continue playing devil's advocate (since I don't really know which
alternative I prefer), I'll also point out that even the largest DTDs, 
like TEI or DocBook, would measure their memory requirements in
kilobytes rather than megabytes; and even-based API makes sense for
the document itself because there is not known limit to an XML
document's size.


All the best,


David
