I agree that the current HTML and HTML+ are suitable for
breaking up a book into nodes as you describe, and we are
planning to do it that way. But HTML and HTML+ as currently
proposed have a flat, not nested, section structure. That
makes it is easy to break up the long stream into parsable
pieces for a modular file structure.

However, several people have suggested making sections
into containers that nest, as with the DocBook and
other DTDs. My question was: if that happens, how
would large books be broken up into modular files?
Having not received a good answer, I will argue to
keep the current flat DTD structure as you have
proposed in HTML+.
