I'm not sure I follow you here.  "Und" means that we have no information
about language, and therefore must use a universal/generic approach
(collate using untailored DUCET, for example).  How is that different from
"zzz" specifying that any language is a possibility here, and therefore
we must use a universal/generic approach?
