I can confirm that this problem still exists in Emacs 28.
It seems to stem from this bit of code:
(defun xmltok-forward ()
(setq xmltok-start (point))
(let* ((case-fold-search nil)
(space-count (skip-chars-forward " \t\r\n"))
(ch (char-after)))
(cond ((eq ch ?\<)
(cond ((> space-count 0)
(setq xmltok-type 'space))
(t
(forward-char 1)
(xmltok-scan-after-lt))))
((eq ch ?\&)
(cond ((> space-count 0)
(setq xmltok-type 'space))
(t
(forward-char 1)
(xmltok-scan-after-amp 'xmltok-handle-entity))))
((re-search-forward "[<&]\\|\\(]]>\\)" nil t)
(cond ((not (match-beginning 1))
So (xmltok-forward) on the ">" will just return `data'. Is it checking
just < and & for validity on purpose? Anybody remember what the thought
process might have been here?
