      Extension Registry for the Extensible Provisioning Protocol

Abstract

   The Extensible Provisioning Protocol (EPP) includes features to add
   functionality by extending the protocol.  It does not, however,
   describe how those extensions are managed.  This document describes a
   procedure for the registration and management of extensions to EPP,
   and it specifies a format for an IANA registry to record those
   extensions.

1.  Introduction

   Domain name registries implement a variety of operational and
   business models.  The differences in these models make it impossible
   to develop a "one size fits all" provisioning protocol; the
   Extensible Provisioning Protocol [RFC5730] was designed to focus on a
   minimal set of common functionality with built-in extension
   capabilities that allow new features to be specified on an "as
   needed" basis.  Guidelines for extending EPP are documented in RFC
   3735 [RFC3735].

   RFCs 3735 and 5730 do not describe how extension development can be
   managed and coordinated.  This has led to a situation in which server
   operators can develop different extensions to address similar needs,
   such as the provisioning of Value Added Tax (VAT) information.
   Clients then need to support multiple extensions that serve similar
   purposes, and interoperability suffers as a result.

   An IANA registry can be used to help manage and coordinate the
   development of protocol extensions.  This document describes an IANA
   registry that will be used to coordinate the development of EPP
   extensions.
