+ <description summary="Assign an application to a particular output">
+ This would allow the compositor to place an application on a particular
+ output, if that output is indeed available. This can happen before
+ application is started which would make the application start on that
+ particular output. If the application is already started it would
+ move the application to that output.
+
+ There's no persistence of this request, once the application terminated
+ you'll need to issue this request again for that particular app_id.

+ See xdg_toplevel.set_app_id from the xdg-shell protocol for a
+ description of app_id.
