But that's impossible _unless_ you restrict yourself to canonic xml.

But it doesn't! You parse _html_ where '<p>' -> '<p/>' ...
Parse your string as xml and you get what you want:

(let ((sink (cxml:make-string-sink)))
  (stp:serialize (cxml:parse "<p><div>some text</div></p>"
(stp:make-builder)) sink)
  (sax:end-document sink))

"<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<p><div>some text</div></p>"
