Without loss of generality the Exec key can point to a script that sets any
environment variable one might want. There is no chance of convincing all DMs
to upgrade to do this based on a new key in the XSession file, nor is this
special purpose mechanism needed.
Speaking of which I have never come across any specification that documents
XSession files. The things I know are that they are in /usr/share/xsessions,
that Type=Application and Type=XSession are allowed, and that Exec works.
Apparently in KDM you can customize the search path. It would make sense if
Comment and Icon and TryExec worked as well but I do not know if those are
implemented in all the places that process these.
It would be good to have that written down as well.
As a general proposition {Not,Only}ShowIn is not proving to be a good idea.
Many of the problem reports we have in LXDE with menu items not showing up are
traced to OnlyShowIn=some other desktop.
