+    <description summary="extends DnD protocol with some advanced features">
+      The zcr_extended_drag_v1 interface extends the Wayland drag-and-drop with
+      features unsurpported by the core protocol. Such as, making toplevel shell
+      surfaces "draggable", as well as making them "snappable" into and out of
+      other surfaces as they are dragged around.
+
+      A common use case for this is a Chromium-like tab/window dragging UX,
+      where the user is able to drag a tab (or any other kind of UI piece) out
+      of its original window, into a new surface anchored to the pointer cursor,
+      similar to a regular drag icon but with enhanced and more configurable
+      capabilities.
+
+      Warning! The protocol described in this file is experimental and
+      backward incompatible changes may be made. Backward compatible changes
+      may be added together with the corresponding uinterface version bump.
+      Backward incompatible changes are done by bumping the version number in
+      the protocol and uinterface names and resetting the interface version.
+      Once the protocol is to be declared stable, the 'z' prefix and the
+      version number in the protocol and interface names are removed and the
+      interface version number is reset.
