+      This global interface allows applications to request the pointer to be
+      moved to a position relative to a wl_surface.
+
+      Note that if the desired behavior is to constrain the pointer to an area
+      or lock it to a position, this protocol does not provide a reliable way
+      to do that. The pointer constraint and pointer lock protocols should be
+      used for those use cases instead.
+
+      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.
