Well, now THIS is interesting.  ISO/DIS 639-3 has no code element "zza", 
but it does have "diq" for Dimli and "kiu" for Kirmanjki (both listed as 
languages of Turkey).  So it appears we have a case where the same 
language(s) is (are) represented by different code elements in 639-2 and 
639-3.

I guess we will add a subtag corresponding to this new 639-2 code 
element, but I'm curious about whether this will force a change in 
639-3, and whether this sort of mismatch could happen after 639-3 goes 
live.  That could make things messy in the Registry in the 3066ter era.
