I've down loaded the updated "The 'indp' Delivery Method for Event
Notifications and Protocol/1.0" document. The versions with revisions are
also in the .zip file for next week's IPP WG meeting and are on the agenda.
The major change was to add the necessary material to be able to register
the 'indp' scheme with IANA (see section 12). Also added client and Printer
conformance requirements for using the 'indp' method, (see section 11).
This document has been in the Area Director's queue since last August, so
this February 28, 2001 version will replace the August 29, 2000 version
according to the IETF procedures for this situation.

Here is the Abstract:
The IPP notification extension document [ipp-ntfy] defines
operations that a client can perform in order to create Subscription Objects
in a Printer and carry out other operations on them. The Subscription Object
specifies that when one of the specified Events occurs, the Printer sends an
asynchronous Event Notification to the specified Notification Recipient via
the specified Delivery Method (i.e., protocol).
The notification extension document [ipp-ntfy] specifies that each
Delivery Method is defined in another document. This document is one such
document, and it specifies the 'indp' Delivery Method and Protocol. This
Delivery Method is a simple protocol consisting of a single operation: the
Send-Notifications operation which uses the same encoding and transport as
IPP. This document defines version '1.0' of the protocol.
For this Delivery Method, when an Event occurs, the Printer
immediately sends (pushes) an Event Notification via the Send-Notifications
operation to the Notification Recipient specified in the Subscription
Object. The Event Notification content consists of Machine Consumable
attributes and a Human Consumable "notify-text" attribute. The Notification
Recipient returns a response to the Printer.
