Re: [regext] Internationalized Email Addresses and EPP

I believe option 2 is the better route to go.  We went with option 2 to extend the password length in RFC 5730 with the Login Security Extension (RFC 8807).  The use of email addresses in EPP is not isolated to RFC 5733.  The Organization Mapping (RFC 8543) and some additional EPP mappings registered in the EPP Extension Registry (Email Forwarding Mapping and NameWatch Mapping) use email addresses.  A new EPP extension could be applied to more than one EPP mapping.  The other question is whether the Internationalized Email Address should be a replacement for or additive to the ASCII Email Address defined in the mappings, based on the email address usage and the support for Internationalized Email Addresses in the underlying protocols and implementations.  An extension could support both replacement and additive options.

    Hi, Scott,

    An interesting question...

    I think it depends upon how you want this to appear from an EPP point of view:

    1. Do you want the EPP standard to support non-ASCII email addresses?

    2. Do you want to *extend* EPP to support non-ASCII email addresses,
    as an option for those who implement the extension?

    For (2), then the EPP extension would be the easiest option, where the
    extension would "update" 5733 and say that the extension changes the
    definition to allow non-ASCII email addresses.  The extension would be
    at Proposed Standard, and 5733 would be at Internet Standard as it is
    now.

    For (1), the best way would be to revise 5733 and change the
    definition of email address syntax, republishing it at Proposed
    Standard and "obsolete" 5733.  The protocol (the new RFC) would then
    be back at Proposed Standard.  You could then do a status change later
    to move the new RFC to Internet Standard (without publishing yet
    another revision).

    So... does the working group want it to appear that support for
    non-ASCII email addresses is an optional extension, or part of the
    base EPP?

RFC 5733 ("Extensible Provisioning Protocol (EPP) Contact Mapping", part of Standard 69) was published in August 2009. It includes a normative reference to RFC 5322 for the definition of email address syntax. RFC 6530 ("Overview and Framework for Internationalized Email") was published in 2012. The regext working group is discussing how we can best update the email address syntax specification in RFC 5733 to add support for the local part of internationalized email addresses to EPP. The EPP XML Schema already "works" as it should, so that doesn't need to change. It's just that pesky normative reference to RFC 5322 that isn't updated by RFC 6530. We think we have a couple of options:
