Re: Categorizing the types of variants

What a generic framework should be? It had better have a general definition to fit every language IDN
registration. So I think to define the type of variants is required.

These types refered here is satisfied the type describe in IDN Admine Guideline for CJK
(draft-jseng-idn-admin) .

If the types of variants is complete, every language could decide which type(s) is needed base
on the language requirment.

As to lead the IDN consistent and decrease confussion,  for a certain language in different TLDs
is strongly recommended to adopt the same variant table and administration guideline.

Total agreement. This is why language working groups and cross-zone
Managers are necessary (every "cn" zones across all the TLDs).

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?
