Does the output need to retain internal parameter entity references, or
may all parameter entity references be expanded?

If the latter, I think there was a program by the name of neko that
should be handy, if you have better luck finding it than I just did: it
translates to XML, expanding all PE references, and you can write a
stylesheet to re-serialize its output in DTD notation.

You could do the same thing with the DTD parser I wrote many years ago
(and last updated about ten years ago), but when I put the source on the
web I seem not to have included any documentation, so you're on your
own:

Sometimes I think I should dust it off and document it, but every time I
do, I also think the time could be more usefully spent writing a
recursive-descent parser for DTDs in XSLT or XQuery.  Someday.
