Hi Dave,
Thanks for your input.
I explored this option, but, unless I'm misunderstanding the documentation, I
don't think I can add an internal DTD subset to chapter.xml, because there is
already one at the top of the book.xml. This is what I intended when I said,

I'm new with XML / DocBook, so maybe I'm misunderstanding you and the
Stackoverflow answer.
