Last I heard (and that was before Dave's patches were incorporated),
PSGML did not deal well at all with the situation where the DTD is

why I spent some time improving sgml-mode.
I believe that Dave's patches do bring PSGML to the point where it
is about as good as sgml-mode when editing text without DTD, so maybe
it is now good enough to replace sgml-mode.

There is no point in even attempting to edit SGML without a DTD,
as a DTD is *required* by ISO 8859 for all processing.

If you need to edit pointy-bracket markup without a DTD, you must
use XML, not SGML.

Given the amount of complaint about PSGML "not indenting and not
highlighting" we have seen on gnu.emacs.help I'd say that the lack
of DTD-less support has been a problem for a long time now.

Who on earth are these people who are trying to edit SGML without
a DTD?

Yes, PSGML should be included in Emacs, and as soon as it truly
works as well (no matter how poor that is) as sgml-mode in
DTD-less settings, we can and should replace sgml-mode with PSGML.

But the DTD-less setting is very important.

It's really irrelevant for SGML. Only XML will work without a DTD.
