+ * Helps the XMLEventsImportContext.
+ *
+ * This class stores
+ * a) the translation from XML event names to API event names, and
+ * 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.
