+      <description summary="hint that existing constraints should be discarded">
+	This request hints to the compositor that the constraints of content
+	updates (CUs) that are currently enqueued in the surface queue should be
+	discarded. See the description of wl_surface.commit for the definition
+	of CUs and per-surface queues.
+
+	This hint is double-buffered state, see wl_surface.commit. It applies to
+	all CUs that are enqueued at the time of the wl_surface.commit request
+	and to their dependencies, excluding the CU created by the
+	wl_surface.commit request itself.
+
+	Clients may use this request to hint that they prioritize the
+	application of the following CUs over previously committed pacing and
+	timing constraints.
+
+	It is compositor policy which constraints are discarded.
