No, sounds reasonable.  I'm just affraid that Web browsers might
not make the distinction.  I.e.  Should a H1 in a BODY be formatted
the same as in a BLOCKQUOTE?

I'll get the later version.

Thanks.

I used a program whose output is different than the list I gave you,
and just re-editted it.  I think I'm getting the motivation to write a
DTD diff program since I already have done the harder work.  But as for
time, it is getting lesser and lesser each day.

I never used it, and don't care that it vanishes.  But somebody might.

I thought of it.  If I can get a decent DTD diff program written (I
should be able to modify dtd2html to generate a different kind of diff
output that it already does), I'd be willing to generate such a
document.  All I need is access to older versions of the DTD.

Thanks for the informative response,
