We will meet on Monday and Tuesday, March 23/24.
I would like to suggest that we attempt to come to some closure the
work in the following way:
1. Assuming the charter as it is stated, we try to agree on what the
system (IDNA2008) looks like. In particular, assuming that mapping is
NOT part of the protocol. I would want also to try to agree on the
basic implications for backward (in)compatibility with the existing
IDNA2003 behavior. This effort is not necessarily a decision-making
one but rather an attempt to agree on the implications of a charter-
consistent design. I would emphasize here that an important component
of the charter was to try to accommodate changes to UNICODE by
algorithmic means (tables, bidi rules, etc) and not have to convene
IETF WGs to agree on any implied changes to the tables
2. Consider the proposal by Paul Hoffman to implement an extension of
IDNA2003 by direct additions or changes to tables of valid characters
or mappings of characters. Again we would want to try to agree on the
implications of this approach.
If we can get this far, I would suggest two further steps. Within the
current charter, I would seek to publish the IDNA2008 as the product
of the WG. However, I would also raise the basic question, which of
the two approaches appears to be most beneficial in terms of
implementation in the short term and maintenance in the longer term. I
would guess that there are different views on these points and perhaps
other or better metrics by which to judge the alternatives. There may
be intermediate alternatives that somehow combine the rule-based
IDNA2008 approach with mapping or other tactics that increase the
backward compatibility of the proposed and current practices.
Your thoughts on this approach would be appreciated.
