+      <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.
+      </description>
+      <request name="create">
+        <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.
