It is not late at all. We are still in IETF Last Call, which is exactly the time we are supposed to be having these community-wide discussions.

No one has suggested that we do that, of course. If someone wants to mis-implement draft-ietf-idnabis-mappings, there is nothing we can do to stop them.

So, what do you propose instead? If this is a proposal to abandon draft-ietf-idnabis-mappings, you need to be more explicit about it. If it is not such a proposal, then you need to say what parts of the draft need to be abandoned to deal with your concern.

I do not feel this is a substantiative change, given the hand-wavyness of wording involoved. If a group of experts in a script say that a particular character "can be mapped to the FULL STOP before label separation occurs" and that its "use as such has ... been investigated thoroughly", then that character is a reasonable addition to our current list of one item.

The IETF Last Call ends on 2009-10-13. There is then a discussion of what suggestions that came up during IETF LC should be incorporated into the various documents. Once the documents reflect the desired changes, the AD passes them along to the IESG for review.
