RFC 9873: Additional Email Address Extension for the Extensible Provisioning Protocol (EPP)

In plain English — editorial summary, not part of the RFC

The Extensible Provisioning Protocol (EPP) does not inherently support internationalized email addresses because the specifications for these addresses did not exist when EPP was developed. This document describes a command-response extension that adds support for associating an additional email address with an EPP contact object. That additional email address can be either an internationalized email address or an ASCII-only address.
