Why stuck?  [1] is an email archive.  Could you summarize in a few
words or is it really complicated?

Granted that DTD models do not incorporate fine-grained specifications
of the type that are important in the EDI side of XML, nonetheless I find
that DTD validation is good for locating structural markup problems, and,
therefore, is helpful to human authors.

With the document side of XML where a DTD model is insufficient, isn't
the tradition to require DTD validation _and_ a noiseless run through
some other form of validating processor?

I think that makes sense for XHTML.  That is, "valid" might, for example,
mean both DTD valid and relax-ng valid.
