If I ever got around to it, DTD validation wouldn't be my approach. I'd
use Jing with Relax NG and a hand-written SAX filter for checking what
Jing cannot check. (text/html could be handled by substituting a parser
that inferred optional tags and appeared to the app as a parser parsing
XHTML--like TagSoup without error recovery.)

You could check the same criteria either manually or using Relax NG.
Using DTDs is not required.

Why bother with DTDs now that Relax NG exists?
