This code, adapted from some code I found on John Kitchin's blog, does
what I want.

** Cross references
#+name: tsd-xref
#+begin_src emacs-lisp
(defun tsd-get-names-and-labels ()
  (interactive)
  (save-excursion
    (goto-char (point-min))
    (let ((matches '()))
      (while (re-search-forward "\\#\\+\\(name\\|label\\):\\s-\\(.*\\)" (point-max) t)
        (add-to-list 'matches (match-string-no-properties 2) t))
      matches)))

(defun tsd-org-insert-crossref-link (&optional arg)
  (interactive (list (completing-read "insert: " (tsd-get-names-and-labels))))
  (insert (format "[[%s]]" arg)))
#+end_src

Now, when I'm referring to something I've labeled or named, I call
tsd-org-insert-crossref-link and helm works on a list of labels and
names defined in the buffer.

It's almost as convenient as using Carsten's reftex mode when writing in
LaTeX.

All the best,
Tom
