While I agree and believe that each language will have their special policy
on management, however I there could still be a more comprehensive framework
that identifies the types of variants that could be categorized.  For
example, for any language (for a given registry/region), there could be two
basic tables:

1. Codepoints Inclusion table: all included codepoints (including necessary
linguistic symbols)
2. Equivalence Set table: codepoint=>{variant set}

>From there, for a zone administrator, there are 4 possible types of reserved
variants generated by a primary domain:
[1] Normal Reserved Variants: blocked from registration, can be activated
into zonefiles
[2] Restricted Reserved Variants: blocked from registration and cannot be
[3] Automatic Zone Variants: automatically included in zonefiles
[4] Suggested Reserved Variants: not blocked for registration, but suggested
by registry

And for zone variants, there are further 3 possible types of management:
(1) Normal Zone Variants: treated as unique domains and can have their own
delegtation NS and child hosts
(2) Same NS: must have same delegation NS as primary domain
(3) Alias Only: set as an alias to the primary domain at the registry

The actual determination (or algorithm if you will) to generate the
resulting variant set for a particular registry/region/language may be
different, but the "types" of variants can be better categorized (especially
to better create a standard provisioning protocol)... and I think these are
the possibilities... can anyone think of any other types?
