Let me clarify that I have never been a DTD-hater. I wish more XML Software
did a better job of supporting or making full use of DTDs.
But the problem I mentioned, how they inhibit embedding one doc in another,
is pretty damning.
I guess the SGML way to work around this would be to parse the DTD (and
document prolog), and merge it into the parent documents DTD. But SGML also
had SUBDOCs, too.
