This document describes an Extensible Provisioning Protocol (EPP) mapping for the provisioning and management of Internationalized Internet domain names (that includes English alphanumeric domain names) stored in a shared central repository. Specified in XML, the mapping defines EPP command syntax and semantics as applied to domain names. More specifically, EPP-IDN intends to provide a mechanism for explicitly managing and provisioning Reserved Variants and Zone Variants created for a Primary Domain Name.
