Thanks, Rasmus. I'll have a look at this and report back. Org -> tex ->
HTML would at least solve the unnumbered heading problem (with the use
of your filter).
As an additional aside, note that Pandoc Markdown permits the use of a
tag to produce an unnumbered heading when exporting to HTML and LaTeX.
# Heading {.unnumbered}
I'm a very inexperienced lisp coder, but it seems to me that this should
be incorporated into the basic exporters. The HTML exporter, for
example, adds the numbering to each heading. In the loop that
accomplishes that, it should be easy to ignore headings with a tag such
as your :nonum:. Otherwise, it is necessary to write a filter that not
only undoes the numbering for selected headlines, but essentially
reproduces the numbering algorithms originally introduced in ox-html.
Cheers,
Alan
