 * b) a mapping from script language names to XMLEventContextFactory objects
 *    (that handle particular languages).
 *
 * Event name translation tables may be added, i.e. they will be joined
 * together. If different translations are needed (i.e., if the same XML name
 * needs to be translated to different API names in different contexts), then
 * translation tables may be saved on a translation table stack.
