+    <description summary="create dialogs related to other toplevels">
+      The xdg_wm_dialog_v1 interface is exposed as a global object allowing
+      to register surfaces with a xdg_toplevel role as "dialogs" relative to
+      another toplevel.
+
+      The compositor may let this relation influence how the surface is
+      placed, displayed or interacted with.
+
+      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.

+    <description summary="dialog object">
+      A xdg_dialog_v1 object is an ancillary object tied to a xdg_toplevel. Its
+      purpose is hinting the compositor that the toplevel is a "dialog" (e.g. a
+      temporary window) relative to another toplevel (see
+      xdg_toplevel.set_parent). If the xdg_toplevel is destroyed, the xdg_dialog_v1
+      becomes inert.
+
+      Through this object, the client may provide additional hints about
+      the purpose of the secondary toplevel. This interface has no effect
+      on toplevels that are not attached to a parent toplevel.

+        interaction with the parent toplevel, and may require a distinct
+        presentation.
+
+        Clients must implement the logic to filter events in the parent
+        toplevel on their own.
+
+        Compositors may choose any policy in event delivery to the parent
+        toplevel, from delivering all events unfiltered to using them for
+        internal consumption.
