OK, thanks for the explanation, Patryk. 

Surely, I am not enough clear.

I am reading the Desktop Entry spec, and more particularly about
OnlyShowIn and NotShowIn keys. This spec refers to a desktop 
environment, and there is a list of "recognized" desktops.

So what I want is not a particular feature, but really a desktop
name (and I do not care of the version of the desktop as the
spec itself does not care).

Do you mean that the "mind/idea" of the spec is that the identification
of the desktop environment is to be made at compile time ?

Even if I am a bit disappointed about that, my question stays:
whether it is at compile time or at runtime, how do we identify
a desktop environment ?

Coming back to the head of this thread, Ted asked for adding
"Unity" to the desktops list for these two keys. If I find a
desktop entry with "OnlyShowIn=Unity", how do I know that I am
running under Unity desktop ?

a) because i/my application have been compiled under Unity ?
b) because i/my application is running under Unity ?

IMHO, the later would be far better than the former. But the 
question is fundamentally the same, isn't ?
