Paul,

Thank you for the clarifications, on today's conference call and on the mailing list.

We have the general question of what, in addition to the base character set specified in rfc1034/1035, drawing on earlier rfcs, letters-digits-and-hyphen, is necessary for constructing labels, for users of latin script.

Our work product will be of the form of some rules for the formation of identifiers, constrained by the limitations on labels arising from the IDNA work of 2003 and 2010.

There may be context-specific rules, perhaps for labels which originate, or terminate, a sequence of labels, e.g., those labels published as part of the IANA root zone and are composed of characters a single script as defined in the current version of UNICODE.

What ever those context-specific rules may be, ours is the general problem of identifiers expressed in the latin script, used to associate resources at public addresses by the protocol defined in rfc1034/1035 and their successors. If a label is terminal, there may be terminal-specific rules.

My understanding is that our peers in the Armenian GP have informed us (via the "similar scripts" question in our common boiler-plate initial document) that there are one or more glyphs common to the Armenian script which are similar to one or more glyphs common to the Latin script. In general this is probably not "news", as whatever the final form of general rules we issue as our work product, our rules are likely to "be aware" that homoglyphs exist, etc.

It is not clear to me that the Latin GP should addressing the issues that were sent to us by the Armenian GP. Here are a few thoughts on the subject.

1) The Integration Panel believes that the Armenian script is separable from the Latin script, according to Section 3.8.3 of the MSR2.

2) Section B.3.4.2 of the LGR Procedures document says "Finally, in investigating the possible variant relations, Generation Panels should ignore cases where the relation is based exclusively on aspects of visual similarity." 

3) Even ignoring the previous two points, the request seems to be for cross-script variants, such as for an Armenian letter that looks like a Latin letter. The "Guidelines for LGR" document indicates that cross-script variants might be created, but gives no hints about why we should do that given that the root zone will consist of labels of a single script (according to Section A.3.1).

This feels to me like the Armenian GP's submission is not related to ours, so we should not be commenting on it.
