      <description summary="Server side window decoration manager">
        This interface allows to coordinate whether the server should create
        a server-side window decoration around a wl_surface representing a
        shell surface (wl_shell_surface or similar). By announcing support
        for this interface the server indicates that it supports server
        side decorations.

        Use in conjunction with zxdg_decoration_manager_v1 is undefined.

        <description summary="Create a server-side decoration object for a given surface">
            When a client creates a server-side decoration object it indicates
            that it supports the protocol. The client is supposed to tell the
            server whether it wants server-side decorations or will provide
            client-side decorations.

            If the client does not create a server-side decoration object for
            a surface the server interprets this as lack of support for this
            protocol and considers it as client-side decorated. Nevertheless a
            client-side decorated surface should use this protocol to indicate
            to the server that it does not want a server-side deco.

              This event is emitted directly after the decoration is created and
              represents the base decoration policy by the server. E.g. a server
              which wants all surfaces to be client-side decorated will send Client,
              a server which wants server-side decoration will send Server.

              The client can request a different mode through the decoration request.
              The server will acknowledge this by another event with the same mode. So
              even if a server prefers server-side decoration it's possible to force a
              client-side decoration.

              The server may emit this event at any time. In this case the client can
              again request a different mode. It's the responsibility of the server to
              prevent a feedback loop.
