1.  Introduction

   This document describes an extension mapping for version 1.0 of the
   Extensible Provisioning Protocol (EPP) [RFC5730].  This EPP mapping
   specifies a flexible schema by which EPP clients and servers can
   reliably validate contact and eligibility data.

   With the increased number of restrictions on contacts and required
   data points (license, ids, etc.) to register a domain name, a way to
   validate the data points prior to issuing a transform command is
   becoming more important.

1.1.  Conventions Used in This Document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   XML is case sensitive.  Unless stated otherwise, XML specifications
   and examples provided in this document MUST be interpreted in the
   character case presented in order to develop a conforming
   implementation.

   In examples, "C:" represents lines sent by a protocol client and "S:"
   represents lines returned by a protocol server.  Indentation and
   white space in examples are provided only to illustrate element
   relationships and are not a REQUIRED feature of this protocol.

2.  Object Attributes

   This extension adds additional elements to EPP object mappings like
   the EPP domain name mapping [RFC5733].  Only those new elements are
   described here.

   Key Value provides a flexible mechanism to share data between the
   client and the server.  The <validate:kv> element defines the data,
   with two required simple attributes, key and value, and an optional
   contactType attribute for specificity in the response, more details
   below.

   o  An example <validate:kv key="VATID" value="0123456789"/>.
   o  An example <validate:kv contactType="Admin" key="contact:cc"
      value="Invalid country code for admin contact, must be MX."/>.

3.  EPP Command Mapping

   A detailed description of the EPP syntax and semantics can be found
   in [RFC5730].  The command mappings described here are specifically
   for the Validate Extension

3.1.  EPP Query Commands

   EPP provides four commands to retrieve object information: <check> to
   determine if an object is known to the server, <info> to retrieve
   detailed information associated with an object, <poll> to discover
   and retrieve service messages queued by the server, and <transfer> to
   retrieve object transfer status information.

3.1.1.  EPP <check> Command

   This extension defines additional elements for the EPP <check>
   command.

   The command frame MAY contain an <extension> element which MAY
   contain one child <validate:check> element with the following child
   element(s):

   o  one or more <validate:contact> element(s) for each contact that is
      to be validated that contains the contact type of the contact to
      be validated.

   The <validate:contact> element MUST contain the following child
   elements:

   o  one <validate:cd> element.
   o  zero or more <validate:kv> elements.

   The <validate:cd> element MUST contain the following child elements:

   o  one <validate:id> element.
   o  an OPTIONAL <validate:postalInfo> element.
   o  an OPTIONAL <validate:voice> element.
   o  an OPTIONAL <validate:fax> element.
   o  an OPTIONAL <validate:email> element.
   o  an OPTIONAL <validate:authInfo> element.
   o  an OPTIONAL <validate:disclose> element.

   <validate> extension.

3.1.4.  EPP <transfer> Command

   This extension does not add any elements to the EPP <transfer>
   command or <transfer> response.

3.2.  EPP Query Commands

   EPP provides five commands to transform objects: <create> to create
   an instance of an object with a server, <delete> to remove an
   instance of an object from a server, <renew> to extend the validity
   period of an object, <transfer> to manage changes in client
   sponsorship of an object, and <update> to change information.

3.2.1.  EPP <create> Command

   This extension does not add any elements to the EPP <create> command
   or <create> response.

3.2.2.  EPP <delete> Command

   This extension does not add any elements to the EPP <delete> command
   or <delete> response.

3.2.3.  EPP <renew> Command

   This extension does not add any elements to the EPP <renew> command
   or <renew> response.

3.2.4.  EPP <transfer> Command

   This extension does not add any elements to the EPP <transfer>
   command or <transfer> response.

3.2.5.  EPP <update> Command

   This extension does not add any elements to the EPP <update> command
   or <update> response.

4.  Formal Syntax

   One schema is presented here that is the EPP Validate Extension
   schema.

   The formal syntax presented here is a complete schema representation
   of the object mapping suitable for automated validation of EPP XML
   instances.  The BEGIN and END tags are not part of the schema; they
   are used to note the beginning and ending of the schema for URI
   registration purposes.

5.2.  EPP Extension Registry

   The EPP extension described in this document should be registered by
   the IANA in the EPP Extension Registry described in [RFC7451].  The
   details of the registration are as follows:

   Name of Extension: "Validate Extension for the Extensible
   Provisioning Protocol (EPP)"

   Document status: Standards Track

   Reference: (insert reference to RFC version of this document)

   Registrant Name and Email Address: IESG, <iesg@ietf.org>

   TLDs: Any

   IPR Disclosure: None

   Status: Active

   Notes: None

6.  Security Considerations

   The mapping extensions described in this document do not provide any
   security services beyond those described by EPP [RFC5730] and
   protocol layers used by EPP.  The security considerations described
   in these other specifications apply to this specification as well.

7.  Acknowledgements

   The authors wish to thank the following persons for their feedback
   and suggestions:

   o  Kevin Allendorf of GoDaddy Inc.
   o  Jody Kolker of GoDaddy Inc.
   o  James Gould of Verisign Inc

8.  Change History

8.1.  Change from 00 to 01

   After review and broad feedback, extensive changes have been made
   transforming the original document from a standalone extension
   command to an extension using the <check> command and response
   framework.
