According to
http://www.freedesktop.org/standards/systemtray/systemtray-spec.html
this is the code a client is supposed to send messages to the system
tray with to make it do stuff.

And XfceSystemTray will be the module containing the System Tray itself
once it is finished, I suppose. Though you think it should go into
xftaskbar for now.

So I think he means, he wants the window manager check for the old kde
property on windows, and if it finds one, generate "new-style" system
tray messages to make the result act as if they were the new one, making
it a proxy.

Sorry for the intrusion ;)
