Of course it is, but OP is referring to features of some software that I
don't have access to, so how am I supposed to make sense of it?  I'm not
going to (i) install a new OS; and (ii) buy/torrent software to understand
and test a feature in named software.

If there's a standard I'm eager to hear about it.

Please give an example of how to specify the language, or an example of a
way to test it that can be done easily from GNU/Linux.

With emacs -q and Org 8.3, and a document with "#+LANGUAGE: da" I get:

     $> exiftool test.pdf | grep -i lang
     Language                        : Danish
