Thanks for advise.  Lennart, do you agree with this change?  I like to
offer help to get this job done (preparing a psgml test release,
testing, documentation).

Thanks for the pointer!  You wrote:

Okay, the tricky part is tp load psgml early enough; this sequence
seems to work for me:

(eval-after-load 'psgml
  ;; Kevin Rodgers <kevinr@ihs.com> in gnu.emacs.help,
  ;; 2001-09-21 10:34:22 PST
  (mapatoms (lambda (symbol)
	      (if (string-match "\\`sgml\\>" (symbol-name symbol))
		  (let ((psgml-symbol (intern (concat "p" (symbol-name symbol)))))
		    (if (boundp symbol)
			(set psgml-symbol (symbol-value symbol)))
		    (if (fboundp symbol)
			(fset psgml-symbol (symbol-function symbol)))
		    (setplist psgml-symbol (symbol-plist symbol))
		    (unintern symbol))))))

(defun ke-psgml-html-mode ()
  "Load psgml first."
  (require 'psgml)
  (html-mode))

(setq auto-mode-alist
      (cons ' ("\\.s?html?\\'" . ke-psgml-html-mode) auto-mode-alist))


Now users have to change all their local variables sections from the
"sgml" namespace:

    <!-- Keep this comment at the end of the file
    Local variables:
    mode: sgml
    sgml-indent-step:1
    End:
    -->

to "psgml" one:

    <!-- Keep this comment at the end of the file
    Local variables:
    mode: psgml
    psgml-indent-step:1
    End:
    -->

But settings in .emacs must continue to use "sgml", or course.
