+    <description summary="extended user interface for Automotive Grade Linux platform">
+      This interface allows another client bind to the agl_shell interface in
+      case there's another shell client already present.
+
+      The client should first bind to this interface and then inform the
+      compositor with the 'doas_shell_client' request and it wants to bind to
+      the agl_shell interface. The client is still expected if using a new
+      version of the agl_shell interface to wait for the 'bound_ok' and
+      'bound_fail' events before issueing any other requests/events.
+
+      Note that this interface has its limitations, and the compositor would
+      still refuse the act for 'set_panel' or 'set_background' requests
+      of the agl_shell interface if there's already a client that used them. Any
+      other requests or events should be delievered and handled as it would
+      a client bound to the agl_shell interface.
