Excellent -- that seems to export just fine.

Interestingly, the export now generates the message, "Position saved to
mark ring, go back with C-c & ."  I presume that comes from the
((org-link-search-inhibit-query t)) argument in the "let" function.  It doesn't
seem to harm the export results.

One of these years I'll have to start poking around the Emacs-Lisp code to
try to puzzle out the workings of the functions being called, especially
org-get-heading
--- is there a comparable one (or arguments) to get the section number of a
heading?

Many thanks, Nicolas.
