I'm doing a lot of DSSSL at the moment, and I wanted the SGML editor
commands to work in DSSSL mode.  With sgml-set-face turned on for
editing SGML structure, doing something like sgml-insert-element
fontifies for SGML up to point instead of fontifying for lisp because
PSGML fontifies as it parses the buffer to figure out the current
element.

I actually wanted it to be mode-local, which emacs doesn't really do,
hence the list of major modes.  When in an SGML mode for editing markup,
I want the SGML to be fontified; when in some other mode for editing
notation data, I want that major mode's font locking to take place.

I can set sgml-set-face in a hook for sgml-mode, but then I have to
unset it if I want to edit in the other mode.  I figured a single list
of modes where SGML should be fontified would be easier to keep track of
than a slue of mode hooks.

I looked into indirect buffers, but this seems more intuitive.
