I'm not sure to understand. Where would he put his options?  Directly on the
heading line, with no "text", then?

Something like this:

--8<---------------cut here---------------start------------->8---
** {10}(3,3)                                           :textpos1:

Contents to position
at some (x,y) coordinates...
--8<---------------cut here---------------end--------------->8---

What do you call a recent Org?  I'm blocked on commit 26a9b02, from May 27th,
as long as the #+SETUPFILE: bug is not fixed (fontification is broken).

So, is that one (4 weeks old) a recent Org?

Aahh!  I wasn't aware (enough) of that way to pass my arguments to my own
environments. Thanks a lot, that works like a charm!

Best regards,
