this is the wrong quote (It's a problem in the `html-close-tag' function
_I wrote_). The problem is that this kind of comment-end token is only
supported by HTML, and not by XML (I don't know about SGML), so I didn't
support this `html-close-tag' (let's discuss this in another mail)

These are the open bug-reports I have about sgml-mode.el:

1. I think there *might* be a bug in line 221 of sgml-mode.el:
    ("<! *--.*-- *>" . font-lock-comment-face)))
In the HTML 4 specification (section 3.2.4), it says that there may
be whitespace between "--" and ">", but not between "<!" and "--".
Since html is sgml, I conclude that the same is true for sgml
(sorry, I can't find the SGML spec)

2. sgml-mode.el currently can't highlight multiline-comments.  This
can probably be fixed by defining a font-lock function. Would that be
too slow ?

3. I wrote a html-close-tag function for html-mode, which
works similar to the `sgml-insert-end-tag' in psgml:

I will reply to you about this in another mail (with the same subject).
