It's arguable whether editing a SGML file counts as "processing"; if
Emacs/psgml or any other editor would actually check the .sgml file
against the DTD at _all_ stages it would be impossible to open some
file or to tag a "plain" test file ;-)

Yes.

Peter exaggerates :)  IIRC, the standard makes some claims about a
"conforming SGML system" and some such things -- but as long as you
don't call Emacs/sgml-mode.el such a system there is nothing to worry
aobut.

Better do it the other way around -- never ever pretend something is
XML if you don't know it for sure.
