	The namespace of GUI specification elements is "`http://www.xmlmind.com/xmleditor/schema/gui`". After downloading and installing the add-on called "XMLmind XML Editor Configuration Pack" using Options → Install Add-ons, the corresponding schema is found in `XXE_user_preferences_dir/addon/xxe_config_pack/gui/xsd/gui.xsd`.
	GUI specification files can be localized by using translation elements. For more information please consult the reference part of this document.
	The layout element has `label` and `icon` attributes specifying the title and desktop icon of the XML editor.
	Without the use of insert, the above `layout` would have been understood as a redefinition from scratch of the standard layout of the XML editor. Such XML editor would have had a blank main window.
