* 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.
