Notification Message Headers and Bundles
draft-ietf-netconf-notification-messages-08
Abstract
This document defines a new notification message format. Included
are:
o a new notification mechanism and encoding to replace the one way
operation of RFC-5277
o a set of common, transport agnostic message header objects.
o how to bundle multiple event records into a single notification
message.
o how to ensure these new capabilities are only used with capable
receivers.

1. Introduction
Mechanisms to support subscription to event notifications have been
defined in [RFC8639] and [RFC8641]. Work on those documents has
shown that notifications described in [RFC7950] section 7.16 could
benefit from transport independent headers. With such headers,
