                       Allocation Token Extension
             for the Extensible Provisioning Protocol (EPP)

Abstract

   This document describes an Extensible Provisioning Protocol (EPP)
   extension for including an Allocation Token in "query" and
   "transform" commands.  The Allocation Token is used as a credential
   that authorizes a client to request the allocation of a specific
   object from the server using one of the EPP transform commands,
   including "create" and "transfer".

1.  Introduction

   This document describes an extension mapping for version 1.0 of the
   Extensible Provisioning Protocol (EPP) [RFC5730].  This mapping,
   which is an extension to EPP object mappings similar to the EPP
   domain name mapping [RFC5731], supports passing an Allocation Token
   as a credential that authorizes a client to request the allocation of
   a specific object from the server using one of the EPP transform
   commands, including "create" and "transfer".

   Allocation is when a server assigns the sponsoring client of an
   object based on the use of an Allocation Token credential.  Examples
   include allocating a registration based on a pre-eligibility
   Allocation Token, allocating a premium domain name registration based
   on an auction Allocation Token, allocating a registration based on a
