-    <description summary="child surface positioner">
-      The xdg_positioner provides a collection of rules for the placement of a
-      child surface relative to a parent surface. Rules can be defined to ensure
-      the child surface remains within the visible area's borders, and to
-      specify how the child surface changes its position, such as sliding along
-      an axis, or flipping around a rectangle. These positioner-created rules are
-      constrained by the requirement that a child surface must intersect with or
-      be at least partially adjacent to its parent surface.
-
-      See the various requests for details about possible rules.
-
-      At the time of the request, the compositor makes a copy of the rules
-      specified by the xdg_positioner. Thus, after the request is complete the
-      xdg_positioner object can be destroyed or reused; further changes to the
-      object will have no effect on previous usages.
-
-      For an xdg_positioner object to be considered complete, it must have a
-      non-zero size set by set_size, and a non-zero anchor rectangle set by
-      set_anchor_rect. Passing an incomplete xdg_positioner object when

-    <description summary="desktop user interface surface base interface">
-      An interface that may be implemented by a wl_surface, for
-      implementations that provide a desktop-style user interface.
-
-      It provides a base set of functionality required to construct user
-      interface elements requiring management by the compositor, such as
-      toplevel windows, menus, etc. The types of functionality are split into
-      xdg_surface roles.
-
-      Creating an xdg_surface does not set the role for a wl_surface. In order
-      to map an xdg_surface, the client must create a role-specific object
-      using, e.g., get_toplevel, get_popup. The wl_surface for any given
-      xdg_surface can have at most one role, and may not be assigned any role
-      not based on xdg_surface.
-
-      A role must be assigned before any other requests are made to the
-      xdg_surface object.
-
-      The client must call wl_surface.commit on the corresponding wl_surface
-      for the xdg_surface state to take effect.
-
-      Creating an xdg_surface from a wl_surface which has a buffer attached or
-      committed is a client error, and any attempts by a client to attach or
-      manipulate a buffer prior to the first xdg_surface.configure call must
-      also be treated as errors.
-
-      After creating a role-specific object and setting it up (e.g. by sending
-      the title, app ID, size constraints, parent, etc), the client must
-      perform an initial commit without any buffer attached. The compositor
-      will reply with initial wl_surface state such as
-      wl_surface.preferred_buffer_scale followed by an xdg_surface.configure
-      event. The client must acknowledge it and is then allowed to attach a
-      buffer to map the surface.
-
-      Mapping an xdg_surface-based role surface is defined as making it
-      possible for the surface to be shown by the compositor. Note that
-      a mapped surface is not guaranteed to be visible once it is mapped.
-
-      For an xdg_surface to be mapped by the compositor, the following
-      conditions must be met:
-      (1) the client has assigned an xdg_surface-based role to the surface
-      (2) the client has set and committed the xdg_surface state and the
-	  role-dependent state to the surface
-      (3) the client has committed a buffer to the surface
-
-      A newly-unmapped surface is considered to have met condition (1) out
-      of the 3 required conditions for mapping a surface if its role surface
-      has not been destroyed, i.e. the client must perform the initial commit
-      again before attaching a buffer.

-	outside of it.
-
-	The window geometry is double-buffered state, see wl_surface.commit.
-
-	When maintaining a position, the compositor should treat the (x, y)

-
-	Once the window geometry of the surface is set, it is not possible to

-
-	If never set, the value is the full bounds of the surface,

-	The arguments are given in the surface-local coordinate space of

-    <description summary="toplevel surface">
-      This interface defines an xdg_surface role which allows a surface to,
-      among other things, set window-like properties such as maximize,
-      fullscreen, and minimize, set application-specific metadata like title and
-      id, and well as trigger user interactive operations such as interactive
-      resize and move.
-
-      A xdg_toplevel by default is responsible for providing the full intended
-      visual representation of the toplevel, which depending on the window
-      state, may mean things like a title bar, window controls and drop shadow.
-
-      Unmapping an xdg_toplevel means that the surface cannot be shown
-      by the compositor until it is explicitly mapped again.
-      All active operations (e.g., move, resize) are canceled and all
-      attributes (e.g. title, state, stacking, ...) are discarded for
-      an xdg_toplevel surface when it is unmapped. The xdg_toplevel returns to
-      the state it had right after xdg_surface.get_toplevel. The client
-      can re-map the toplevel by performing a commit without any buffer
-      attached, waiting for a configure event and handling it as usual (see
-      xdg_surface description).

-      A popup surface is a short-lived, temporary surface. It can be used to
-      implement for example menus, popovers, tooltips and other similar user
-      interface concepts.
-
-      A popup can be made to take an explicit grab. See xdg_popup.grab for
-      details.
-
-      When the popup is dismissed, a popup_done event will be sent out, and at
-      the same time the surface will be unmapped. See the xdg_popup.popup_done
-      event for details.
-
-      Explicitly destroying the xdg_popup object will also dismiss the popup and
-      unmap the surface. Clients that want to dismiss the popup when another
-      surface of their own is clicked should dismiss the popup using the destroy
-      request.
-
-      A newly created xdg_popup will be stacked on top of all previously created
-      xdg_popup surfaces associated with the same xdg_toplevel.
-
-      The parent of an xdg_popup must be mapped (see the xdg_surface
-      description) before the xdg_popup itself.
-
-      The client must call wl_surface.commit on the corresponding wl_surface
-      for the xdg_popup state to take effect.

-	This request makes the created popup take an explicit grab. An explicit
-	grab will be dismissed when the user dismisses the popup, or when the
-	client destroys the xdg_popup. This can be done by the user clicking
-	outside the surface, using the keyboard, or even locking the screen
-	through closing the lid or a timeout.
-
-	If the compositor denies the grab, the popup will be immediately
-	dismissed.
-
-	This request must be used in response to some sort of user action like a
-	button press, key press, or touch down event. The serial number of the
-	event should be passed as 'serial'.
-
-	The parent of a grabbing popup must either be an xdg_toplevel surface or
-	another xdg_popup with an explicit grab. If the parent is another
-	xdg_popup it means that the popups are nested, with this popup now being
-	the topmost popup.
-
-	Nested popups must be destroyed in the reverse order they were created
-	in, e.g. the only popup you are allowed to destroy at all times is the
-	topmost one.
-
-	When compositors choose to dismiss a popup, they may dismiss every
-	nested grabbing popup as well. When a compositor dismisses popups, it
-	will follow the same dismissing order as required from the client.
-
-	If the topmost grabbing popup is destroyed, the grab will be returned to
-	the parent of the popup, if that parent previously had an explicit grab.
-
-	If the parent is a grabbing popup which has already been dismissed, this
-	popup will be immediately dismissed. If the parent is a popup that did
-	not take an explicit grab, an error will be raised.
-
-	During a popup grab, the client owning the grab will receive pointer
-	and touch events for all their surfaces as normal (similar to an
-	"owner-events" grab in X11 parlance), while the top most grabbing popup
-	will always have keyboard focus.
