No, no, no. Xsession is invoked by the display manager (DM) as you
said (or by startx). Its job is to... uh... get the session running
(window manager, environment, ssh and/or gpg agent, session dbus
(not on my box ;-) that kind of thing -- it used to "do" desktop
environments last time I looked, but that's a while ago)

So far I agree with you :-)

As part of that, it "typically" (that is configurable!) it looks
whether there is a user session RC (typically -- also configurable!)
called ~/.xsessionrc and *sources* it, as part of the session start
up process. The "sourcing" part is important, otherwise you couldn't
set environment variables which get inherited by all your session's
processes.

See man (5) Xsession and poke a bit through the scripts in
/etc/X11/Xsession.d/, then have a look at /etc/X11/Xsession.options,
then at /etc/X11/Xsession.
