1.  Introduction

   This document defines a YANG data model for NETCONF Event
   Notifications [RFC5277].  The notification structure defined in
   [RFC5277] uses a XML Schema [W3C.REC-xml-20001006] allowing to encode
   and validate the message in XML.  Nevertheless, when the notification
   message is encoded using other encodings such as JSON [RFC8040] or
   CBOR [RFC9254], a YANG model to validate or encode the message is
   necessary.  This document extends [RFC5277], defining the NETCONF
   Event Notification structure in a YANG module.

2.  YANG Module

2.1.  YANG Tree Diagram

   This YANG module adds a structure with one leaf for the datetime as
   defined in section 2.2.1 of [RFC5277].

   module: ietf-notification

     structure notification:
       +-- eventTime    yang:date-and-time

3.  Security Considerations

   The security considerations for the NETCONF Event notifications are
   described in [RFC5277].  This documents adds no additional security
   considerations.

4.  IANA Considerations

   This document describes the URI used for the IETF XML Registry and
   registers a new YANG module name.

4.1.  URI

   IANA is requested to add this document as a reference in the
   following URI in the IETF XML Registry [RFC3688].

   URI: urn:ietf:params:xml:ns:netconf:notification:1.0
   Registrant Contact: The IESG.
   XML: N/A; the requested URI is an XML namespace.
   Reference: RFC5277; RFC-to-be

4.2.  YANG module name

   This document registers the following YANG module in the YANG Module
   Names Registry [RFC6020], within the "YANG Parameters" registry:
