Thanks for the quick answer and for these hints.

In this particular situation (the \subtitle will always be document
specific) the latex class is not possible here -- I won't create latex
classes per document.

An include file just for a subtitle seems overkill.  So I went with the
macro.  If there were multiple offending lines, I'd probably use the
include file.

Anyway, just for reference, this is the macro:
#+begin_src org
#+MACRO: subtitle #+latex_header: \subtitle{$1}
{{{subtitle(foo)}}}
#+end_src

Downside is, that \ and , within the subtitle will have to be escaped.

Regards,
Andreas
