What is the `purecopy' in your code good for? You didn't change this
in the source code, did you? ;-)

I would do it with a simple bit of Elisp.  You could put something
like the following into your ~/.emacs:

(defun my-html-forward-sentence ()
    (if (re-search-forward "\\([.?!]\\)<" nil t)
        (goto-char (match-end 1))
      (goto-char (point-max)))))

(define-key sgml-mode-map (kbd "M-e") 'my-html-forward-sentence)
