How to flatten a DTD to one file

[Chris Maloney <voldrani@gmail.com>]

Hi, all,

Is there an easy, robust way to create a flattened, single-file DTD out of a modular, multi-file one?

I thought this was possible using xmllint, but I've just spent a couple of hours, and I can't find find the trick, if there is one.

Thanks!
