 * # GtkTextTagTables as GtkBuildable
 * 
 * The GtkTextTagTable implementation of the GtkBuildable interface
 * supports adding tags by specifying “tag” as the “type” attribute
 * of a <child> element.
 * 
 * An example of a UI definition fragment specifying tags:
 * |[
 * <object class="GtkTextTagTable">
 * <child type="tag">
 * <object class="GtkTextTag"/>
 * </child>
 * </object>
 * ]|
