Hi there,

another option might be to remove the num:nil org option and instead
tell latex not to number any sections by setting secnumdepth to 0.

so for instance

---start org file -----------
#+TITLE: Test
#+OPTIONS:  toc:t
#+LATEX_HEADER: \setcounter{secnumdepth}{0}

* Part 1
Some text

* Part 2
Some more text
---end org file -----------

should do the trick.

the only drawback is that one still needs the num:nil option for the
other export formats.

perhaps this could become another way to implement num:nil for the latex
export in general. though i don't think it would work reliably for just a
subtree then.

Greets,
Jonas
