The standards for Internationalized Domain Names in Applications
(IDNA) require a review of each new version of Unicode to determine
whether incompatibilities with prior versions or other issues exist
and, where appropriate, to allow the IETF to decide on the trade-offs
between compatibility with prior IDNA versions and compatibility with
Unicode going forward.  That requirement, and its relationship to
tables maintained by IANA, has caused significant confusion in the
past.  This document makes adjustments to the review procedure based
on experience and updates IDNA, specifically RFC 5892, to reflect
those changes and to clarify the various relationships involved.  It
also makes other minor adjustments to align that document with

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track

for improvements.  Please refer to the current edition of the Official
