Orie, would you or someone else please provide a description of the needed 
changes that you described below? The IESG evaluation record isn’t visible in 
the Datatracker, so that doesn’t help.



From what I recall, the goal of this draft is to define an EPP extension that 
adds support for SMTPUTF8 email addresses. The RFC5733 XML schema already 
supports UTF8, but we have an issue because this text exists in 5733:



“Email address syntax is defined in [RFC5322].”



5322 isn’t being updated to include support for SMTPUTF8 email addresses, so 
5733 is stuck with the current ASCII-only syntax specification.



The current draft is very focused on EAI and i18n. If that’s where the issues 
are, would it help if the draft were less about EAI and more about adding 
support for a second email address that could be either an all-ASCII address or 
an SMTPUTF8 address? This would ensure that there’s always an all-ASCII address 
specified in the associated contact object if an SMTPUTF8 address appears in 
the extension. It could also be used to capture a second all-ASCII address 
might be useful in account recovery, for example, if the primary address 
becomes unreachable. The extension schema could be as simple as something like 
this:



<CODE BEGINS>

<?xml version="1.0" encoding="UTF-8"?>

<schema xmlns=http://www.w3.org/2001/XMLSchema

  xmlns:altEmail="urn:ietf:params:xml:ns:epp:altEmail-1.0"

  targetNamespace="urn:ietf:params:xml:ns:epp:altEmail-1.0"

  elementFormDefault="qualified">

  <annotation>

    <documentation>Extensible Provisioning Protocol v1.0

       alternative email address schema.</documentation>

  </annotation>

  <!-- Create, Update, and Info Response extension element -->

  <element name="altEmail" type="altEmail:altEmailType" />

  <!--

    Single email element that can be empty

   -->

  <complexType name="altEmailType">

    <attribute name="primary" type="boolean" default="false"/>

    <sequence>

      <element name="email" type="token"/>

    </sequence>

  </complexType>

  <!--

End of schema.

-->

</schema>

<CODE ENDS>



The “altEmail” element can be used to provision a second email address that can 
be either all-ASCII or SMPUTF8. The “primary” attribute could be used to 
identify the extension address as the primary address for contact purposes. 
This could be used to mark an SMTPUTF8 address as primary. Is this worth 
exploring?

Hello,

https://datatracker.ietf.org/doc/draft-ietf-regext-epp-eai/<https://secure-web.cisco.com/1L9IEHAcZBCB67r1r37qJqg1NnDjdFRCh-fzxdrEFG65g1fXXEkgzxVC4SusImF2bLUGTs7-bcCafkZz2WsjI0otx3bzFifhjwa1opylcM-sn_SVtjIGq1zwr-4Z4eTc9teZg5LcHB9tG6ky-hyTJjE-O2g8wDft8ZkJ62bEjFFoiCeisZOdUvxKYVRj_S8_zT6ppqo5mir0vaNJ_NfGGvxVnkYZbcjNtHL-AG26ISrVgobAci0TkJnDXFe09oSvkMVBW8jUzizoQJqXZGFGpOYZ8igOx8PCqS4nw2gEV7uwremToG5th5THsrX4To0VA/https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-ietf-regext-epp-eai%2F>

I am moving the document back to the working group.

Thanks to all who provided feedback and reviews on this draft, and for your 
patience and support for our process.

This document has been stuck in AD Followup, but the changes discussed are 
substantial enough that I believe the working group needs to address them, and 
then WG consensus needs to be re-established.

I suggest requesting an early review from ART ART, with a focus on i18n.

I'd like to see that review addressed before the document shepherd writeup is 
revised, and the document is submitted for AD Evaluation.

Chairs, please add a milestone to submit a revised "Use of Internationalized 
Email Addresses in the Extensible Provisioning Protocol (EPP)", to the IESG 
before 2025.

I'll work with you all to ensure that the document, and the associated i18n 
issues are addressed in a timely manner.

Regards,

OS, ART AD
