1.  Introduction

   This document describes a Validate 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

   A EPP validation object has attributes and associated values that can
   be viewed by the client.  This section describes each attribute type
   in detail.

2.1.  Key Value

   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 three 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, and <transfer> to
   retrieve object transfer status information.

3.1.1.  EPP <check> Command

   The EPP <check> command is used to validate a list of contact
   information.  The <check> command MUST contain a <validate:check>
   element that identifies the validate namespace.  The <validate:check>
   element contains the following child elements:

   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.

   The following is an example <check> command.

3.1.2.  EPP <info> Command

   Info semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <info> command.

3.1.3.  EPP <transfer> Command

   Transfer semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <transfer> command.

3.2.  EPP Transform 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

   Create semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <create> command.

3.2.2.  EPP <delete> Command

   Delete semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <delete> command.

3.2.3.  EPP <renew> Command

   Renew semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <renew> command.

3.2.4.  EPP <transfer> Command

   Transfer semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <transfer> command.

3.2.5.  EPP <update> Command

   Update semantics do not apply to validate objects, so there is no
   mapping defined for the EPP <update> command.

4.  Formal Syntax

   One schema is presented here that is the EPP Validate 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.

4.1.  Validate Schema

   BEGIN
   <?xml version="1.0" encoding="UTF-8"?>

5.  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.

6.  IANA Considerations

6.1.  XML Namespace

   This document uses URNs to describe XML namespaces and XML schemas
   conforming to a registry mechanism described in [RFC3688].  The
   following URI assignment is requested of IANA:

   URI: ietf:params:xml:ns:validate-1.0

   Registrant Contact: See the "Author's Address" section of this
   document.

   XML: See the "Formal Syntax" section of this document.

7.  Implemntation Status

   Note to RFC Editor: Please remove this section and the reference to
   [RFC6982] before publication.

   This section records the status of known implementations of the
   protocol defined by this specification at the time of posting of this
   Internet-Draft, and is based on a proposal described in [RFC6982].
   The description of implementations in this section is intended to
   assist the IETF in its decision processes in progressing drafts to
   RFCs.  Please note that the listing of any individual implementation
   here does not imply endorsement by the IETF.  Furthermore, no effort
   has been spent to verify the information presented here that was
   supplied by IETF contributors.  This is not intended as, and must not
   be construed to be, a catalog of available implementations or their
   features.  Readers are advised to note that other implementations may
   exist.

   According to [RFC6982], "this will allow reviewers and working groups
   to assign due consideration to documents that have the benefit of
   running code, which may serve as evidence of valuable experimentation
   and feedback that have made the implemented protocols more mature.
   It is up to the individual working groups to use this information as
   they see fit".

7.1.  To Be Filled In

   Add implementation details once available.

8.  Acknowledgements

   and suggestions:

   o  Kevin Allendorf of GoDaddy Inc.
   o  Jody Kolker of GoDaddy Inc.

9.2.  Change from 01 to 02

   Corrected some formatting issues.

9.3.  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 using the <check> command and response framework.  Stubbed
   in an Implementation section for later documentation.

9.4.  Change from carney-regext 01 to ietf-regext 00

   Updated miscellaneous verbiage to reflect the change from an
   extension and changed to ietf naming as REGEXT WG will assume this
   work.
