Thanks for the hint, this does the job:

#+begin_src emacs-lisp
  (" " . (outshine-use-outorg
          (lambda ()
            (message
             "%s" (substring-no-properties
                   (org-display-outline-path))))
          'WHOLE-BUFFER-P))
#+end_src

only that promptly another message is shown (I can't use sit-for in
the program):

I have to get rid of that one ...
