The LaTeX classes with which I'm familiar all ensure that the TOC
entry matches the in-text heading wrt numbered/unnumbered.  I think this
is a principle of document design (which might of course be subverted
for some purpose).

Is it the case that ODT lacks the distinction made by LaTeX between,
say, \section and \section*?  The former is numbered if its depth <=
secnumdepth and unnumbered otherwise.  It appears in the TOC if its
depth is <= tocdepth, regardless of whether or not it is numbered.  The
numbering of depths is determined by the class, because the number and
kinds of sections vary by document class.  Numbering isn't something the
user thinks about--it is set by the sectioning command, according to the
class file.

The \section* form is a special case.  It produces an unnumbered heading
that does not appear in the TOC.
