4.  Formal Syntax

   The EPP Launch Phase Mapping schema is presented in Section 4.1.

   The formal syntax presented 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.  IANA Considerations

5.1.  XML Namespace

   This document uses URNs to describe XML namespaces and XML schemas
   conforming to a registry mechanism described in [RFC3688].

   IANA has registered the launch namespace as follows:

      URI: urn:ietf:params:xml:ns:launch-1.0

      Registrant Contact: IESG

      XML: None.  Namespace URIs do not represent an XML specification.

   IANA has registered the launch XML schema as follows:

      URI: urn:ietf:params:xml:schema:launch-1.0

      Registrant Contact: IESG

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

5.2.  EPP Extension Registry

   IANA has registered the EPP extension described in this document in
   the "Extensions for the Extensible Provisioning Protocol (EPP)"
   registry described in [RFC7451].  The details of the registration are
   as follows:

   Name of Extension: "Launch Phase Mapping for the Extensible
   Provisioning Protocol (EPP)"

   Document Status: Standards Track

   Reference: RFC 8334

   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], the EPP
   domain name mapping [RFC5731], and protocol layers used by EPP.  The
   security considerations described in these other specifications apply
   to this specification as well.

   Updates to, and deletion of, an application object MUST be restricted
   to clients authorized to perform the said operation on the object.

   Information contained within an application, or even the mere fact
   that an application exists, may be confidential.  Any attempt to
   operate on an application object by an unauthorized client MUST be
   rejected with an EPP 2201 (authorization error) return code.  Server
   policy may allow an <info> operation with filtered output by clients

   other than the sponsoring client, in which case the <domain:infData>
   and <launch:infData> responses SHOULD be filtered to include only
   fields that are publicly accessible.
