 * roughly described by the following DTD.
 *

 * ]|
 * 
 * There are some additional restrictions beyond those specified in the
 * DTD, e.g. every toolitem must have a toolbar in its anchestry and
 * every menuitem must have a menubar or popup in its anchestry. Since
 * a #GMarkupParser is used to parse the UI description, it must not only
 * be valid XML, but valid markup.
 * 
 * If a name is not specified, it defaults to the action. If an action is
 * not specified either, the element name is used. The name and action
 * attributes must not contain “/” characters after parsing (since that
 * would mess up path lookup) and must be usable as XML attributes when
 * enclosed in doublequotes, thus they must not “"” characters or references
 * to the &quot; entity.
 * 
 * # A UI definition #
 * 
 * |[
 * <ui>
 * <menubar>
 * <menu name="FileMenu" action="FileMenuAction">
 * <menuitem name="New" action="New2Action" />
 * <placeholder name="FileMenuAdditions" />
 * </menu>
 * <menu name="JustifyMenu" action="JustifyMenuAction">
 * <menuitem name="Left" action="justify-left"/>
 * <menuitem name="Centre" action="justify-center"/>
 * <menuitem name="Right" action="justify-right"/>
 * <menuitem name="Fill" action="justify-fill"/>
 * </menu>
 * </menubar>
 * <toolbar action="toolbar1">
 * <placeholder name="JustifyToolItems">
 * <separator/>
 * <toolitem name="Left" action="justify-left"/>
 * <toolitem name="Centre" action="justify-center"/>
 * <toolitem name="Right" action="justify-right"/>
 * <toolitem name="Fill" action="justify-fill"/>
 * <separator/>
 * </placeholder>
 * </toolbar>
 * </ui>
 * ]|
 * 
 * The constructed widget hierarchy is very similar to the element tree
 * of the XML, with the exception that placeholders are merged into their
 * parents. The correspondence of XML elements to widgets should be
 * almost obvious:
 * 
 * - menubar
 * 
 * a #GtkMenuBar
 * 
 * - toolbar
 * 
 * a #GtkToolbar
 * 
 * - popup
 * 
 * a toplevel #GtkMenu
 * 
 * - menu
 * 
 * a #GtkMenu attached to a menuitem
 * 
 * - menuitem
 * 
 * a #GtkMenuItem subclass, the exact type depends on the action
 * 
 * - toolitem
 * 
 * a #GtkToolItem subclass, the exact type depends on the
 * action. Note that toolitem elements may contain a menu element,
 * but only if their associated action specifies a
 * #GtkMenuToolButton as proxy.
 * 
 * - separator
 * 
 * a #GtkSeparatorMenuItem or #GtkSeparatorToolItem
 * 
 * - accelerator
 * 
 * a keyboard accelerator
 * 
 * The “position” attribute determines where a constructed widget is positioned
 * wrt. to its siblings in the partially constructed tree. If it is
 * “top”, the widget is prepended, otherwise it is appended.
 * 
 * # UI Merging # {#UI-Merging}
 * 
 * The most remarkable feature of #GtkUIManager is that it can overlay a set
 * of menuitems and toolitems over another one, and demerge them later.
 * 
 * Merging is done based on the names of the XML elements. Each element is
 * identified by a path which consists of the names of its anchestors, separated
 * by slashes. For example, the menuitem named “Left” in the example above
 * has the path `/ui/menubar/JustifyMenu/Left` and the
 * toolitem with the same name has path
 * `/ui/toolbar1/JustifyToolItems/Left`.
 * 
 * # Accelerators #
 * 
 * Every action has an accelerator path. Accelerators are installed together
 * with menuitem proxies, but they can also be explicitly added with
 * <accelerator> elements in the UI definition. This makes it possible to
 * have accelerators for actions even if they have no visible proxies.
 * 
 * # Smart Separators # {#Smart-Separators}
 * 
 * The separators created by #GtkUIManager are “smart”, i.e. they do not show up
 * in the UI unless they end up between two visible menu or tool items. Separators
 * which are located at the very beginning or end of the menu or toolbar
 * containing them, or multiple separators next to each other, are hidden. This
 * is a useful feature, since the merging of UI elements from multiple sources
 * can make it hard or impossible to determine in advance whether a separator
 * will end up in such an unfortunate position.
 * 
 * For separators in toolbars, you can set `expand="true"` to
 * turn them from a small, visible separator to an expanding, invisible one.
 * Toolitems following an expanding separator are effectively right-aligned.
 * 
 * # Empty Menus
 * 
 * Submenus pose similar problems to separators inconnection with merging. It is
 * impossible to know in advance whether they will end up empty after merging.
 * #GtkUIManager offers two ways to treat empty submenus:
 * 
 * - make them disappear by hiding the menu item they’re attached to
 * 
 * - add an insensitive “Empty” item
 * 
 * The behaviour is chosen based on the “hide_if_empty” property of the action
 * to which the submenu is associated.
 * 
 * # GtkUIManager as GtkBuildable # {#GtkUIManager-BUILDER-UI}
 * 
 * The GtkUIManager implementation of the GtkBuildable interface accepts
 * GtkActionGroup objects as <child> elements in UI definitions.
 * 
 * A GtkUIManager UI definition as described above can be embedded in
 * an GtkUIManager <object> element in a GtkBuilder UI definition.
 * 
 * The widgets that are constructed by a GtkUIManager can be embedded in
 * other parts of the constructed user interface with the help of the
 * “constructor” attribute. See the example below.
 * 
 * ## An embedded GtkUIManager UI definition
