+      <description summary="set the application with a split orientation">
+        This requests asks the compositor to change the application from the
+        original mode (whatever that might be) to a split, tiled orientation
+        mode defined in the tile orientation enum.
+        Clients need to implement resizing (to handle xdg-shell configure
+        events) for this to work correctly.
+
+        This request only handles a single level of tiling for practical
+        reasons: to keep implementation simple and straight forward. The
+        compositor will ignore requests if there are already two windows
+        present. The client can verify this request succeed by checking the
+        xdg-shell configure event and with it, the states sent
+        by the compositor.
+
+        If there's no app_id with the supplied name, the compositor will add
+        the app to a pending list in order to be applied when an application
+        gets started, or if the application sets its application after the
+        initial wl_surface.commit request.
+
+        Applications can use this approach if they want to be started in a
+        tiled orientation position, before creating the xdg-shell toplevel role.
+
+        A none orientation type would make the window go back to the original
+        maximized mode. If two windows are side by side, returning one of them
+        back the original mode would mean the other one will be made hidden
+        and the one doing the request for the none orientation will become
+        the currently active window. A further activation, using activate_app
+        request for the other window would make that one active.
+
+        Closing the window in the tiled orientation state implies that either
+        the background surface will displayed, or in case there was another
+        applications being shown at that time, will make that application be
+        returned to the original, maximized state.
+
+        The tiled orientation could be applied independently of each other,
+        such that a client can transition from one tiled orientation to
+        another. Note that any other window already present would literally
+        take the opposite orientation with the one currently being changed. So
+        tiled orientation modification automatically implies a tile orientation
+        for any other application already present/active at that time.
+
+        In case there's already a client active at that time, it will be
+        attributed automatically the opposite tiled orientation, such that two
+        concurrent applications can be displayed at the same time.
+
+        The orientation tiles can not be combined, and only state at a time
+        can be active. Only horizontal and vertical tiling is possible. A
+        horizontal and vertical tile orientation simultaneously is not
+        possible.
+
+        Input focus is being delivered to the last started/activated window,
+        such that users can cycle between that one or the other, assumes there's
+        another window in the first place.
+
+        A width size can also be specified for the split window. Note that this
+        width can't exceed the output width value, or the compositor can choose
+        to ignore this value.
+
+        Making the split window sticky would inform the compositor that the
+        window should always be active when switching or when activating between
+        other windows. This would allow navigating, starting and activating other
+        windows while keeping the current window always in a split state.
+
+        See xdg_toplevel.set_app_id from the xdg-shell protocol for a
+        description of app_id.
