You sound wistful for a subset of DTD syntax that is useful for
novels and recipies.  :-)  Do we *really* need <!NOTATION>
declarations? Are IDs best defined in <!ENTITY> declarations?  And
what about unparsed entities?  Conditional sections?  Mixed content

DTDs may have one saving grace, but they have many more flaws.

Sounds like you want to keep the bath water just to save the
baby.  DTDs have a lot of warts, they don't really fit XML
documents very well, and they don't mesh well with XML data at all.

RelaxNG is probably the way to go.  It's starting to look like the 
multiple uses of XML demand multiple schema languages, not one
XML Schema language which binds us all.  A simple DTD schema language
(with XML Syntax) would probably be the best mesh for the problem
space you describe; rote translation to XML Schema / RelaxNG should
solve the interoperability issues.
