+    <description summary="fullscreen shell">
+      This interface provides a mechanism for a client to display simple
+      full-screen surfaces.
+
+      This protocol can be used by nested compositors. For instance, a simple
+      full-screen compositor might delegate content to a client. Another
+      example would be a compositor delegating parts of its content to a
+      client, for example drawing a status bar icon might be delegated to a
+      client. The compositor dictates the size of the content.
+
+      Warning! The protocol described in this file is currently in the testing
+      phase. Backward compatible changes may be added together with the
+      corresponding interface version bump. Backward incompatible changes can
+      only be done by creating a new major version of the extension.
