OK - that I see how this works. Although I would very much like to have a syntax to define this
default language header as #+PROPERTY as it would be more consistent.
But I remember there was a way of executing this code when opening but I can't find it anymore.

I think that would be a very important and useful aspect to include.

Just an idea: if one would add a second value to the :session argument, one could use that one th
specify the language for the session. If none is given, it would apply to all languages (so
nothing changes), but if one is given, it would only apply to this language:
#+PROPERTY: :session R-test R
#+PROPERTY: :session none
would set the language specific header :session to R-test, and the "old" session argument to "none",

If implemented as above, the default behavior would not be changed, so no changes need to be done
by the user.
In addition, this could be extended to other language specific headers (the only problem could be
header arguments which take anyway multiple arguments, like :results).
Cheers,
Rainer
