/** Constructing menus and toolbars from an XML description.
 *
 * A Gtk::UIManager constructs a user interface (menus and toolbars) from one or more UI definitions,
 * which reference actions from one or more action groups.
 *
 * \par UI Definitions
 *
 * The UI definitions are specified in an XML format which can be roughly described by the following DTD.
 * \code
 * <!ELEMENT ui          (menubar|toolbar|popup|accelerator)* >
 * <!ELEMENT menubar     (menuitem|separator|placeholder|menu)* >
 * <!ELEMENT menu        (menuitem|separator|placeholder|menu)* >
 * <!ELEMENT popup       (menuitem|separator|placeholder|menu)* >
 * <!ELEMENT toolbar     (toolitem|separator|placeholder)* >
 * <!ELEMENT placeholder (menuitem|toolitem|separator|placeholder|menu)* >
 * <!ELEMENT menuitem     EMPTY >
 * <!ELEMENT toolitem     (menu?) >
 * <!ELEMENT separator    EMPTY >
 * <!ELEMENT accelerator  EMPTY >
 * <!ATTLIST menubar      name                  #IMPLIED 
 *                      action                #IMPLIED >
 * <!ATTLIST toolbar      name                  #IMPLIED 
 *                      action                #IMPLIED >
 * <!ATTLIST popup        name                  #IMPLIED 
 *                      action                #IMPLIED >
 * <!ATTLIST placeholder  name                  #IMPLIED
 *                       action                #IMPLIED >
 * <!ATTLIST separator    name                  #IMPLIED
 *                       action                #IMPLIED
 *                       expand   (true|false) #IMPLIED >
 * <!ATTLIST menu         name                  #IMPLIED
 *                       action                #REQUIRED
 *                       position (top|bot)    #IMPLIED >
 * <!ATTLIST menuitem     name                  #IMPLIED
 *                      action                #REQUIRED
 *                      position (top|bot)    #IMPLIED >
 * <!ATTLIST toolitem     name                  #IMPLIED
 *                      action                #REQUIRED
 *                      position (top|bot)    #IMPLIED >
 * <!ATTLIST accelerator  name                  #IMPLIED
 *                       action                #REQUIRED >
 * \endcode
 *
 * 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 GMarkup parser is used to parse the UI description, 
 * it must not only be valid XML, but valid GMarkup.
 *
 * 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.
 *
 * \par Example: UI Definition
 * \code
 * <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>
 * \endcode
 * 
 * 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 Gtk::MenuBar
 * - toolbar 	a Gtk::Toolbar
 * - popup  a toplevel Gtk::Menu
 * - menu  a Gtk::Menu attached to a menuitem
 * - menuitem  a Gtk::MenuItem subclass, the exact type depends on the action
 * - toolitem  a Gtk::ToolItem 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 Gtk::MenuToolButton as proxy.
 * - separator  a Gtk::SeparatorMenuItem or Gtk::SeparatorToolItem
 * - 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. 
 *
 * \par UI Merging
 *
 * The most remarkable feature of Gtk::UIManager 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.
 *
 * \par 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.
 * 
 * \par Smart Separators
 *
 * The separators created by Gtk::UIManager 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.
 *
 * \par 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. Gtk::UIManager offers 
 * two ways to treat empty submenus:
 *
