I am talking about two main labels that are not variants of each other,
but share a variant. For example, a multilanguage zone that support both
Arabic and Persian will have something like this in its equivalence data
The first two characters are only used in the Arabic languages, and the
third is only used in Persian. The above data is necessary if you want
to distinguish the first two (that are distinguished in Arabic), but avoid
security problems (U+06CC looks *identical* to U+0649 in isolated and
final contextual forms, and *identical* to U+064A in medial and initial
Now, when one registers a label with a U+0649 and someone else goes with a
U+064A, who will own the U+06CC version?

I like to see a standard that limits each zone to a specific *language*,
but I guess that can't happen in situations like a Swiss or European zone.
But also, I like to see a nice mechanism or some guideline for a Swiss
registry: "Grab the Italian, French, and German and merge them
according to the following guidelines." The guidelines may require a
language priority list or whatever, but it should be usable in a
