Today, 8/19/99, the IETF IPP WG made a few more changes to the IPP
Notification Attribute Summary.

I've reposted it at:

Here are the changes:

1.1 Changed made to the 8/17/99 version to make the 8/19/99 version
1. Added "notify-content-type" (mimeMediaType) so that
the client can specify whether human consumable versus machine consumable.
2. Added "notify-content-type-supported" (1setOf
collection) Printer Description attribute to represent which notification
format types are supported for each supported delivery scheme.
3. Made Per-Printer Subscriptions and the Subscription
object REQUIRED if notification is supported. So both Per-Job and
Per-Printer subscriptions are REQUIRED. There is no longer any
CONDITIONALLY REQUIRED indication in our spec.
4. Added "notify-attributes-charset" to represent
"attributes-charset" in subscription requests and objects to distinguish it
from the request's "attributes-charset" attribute.
5. Added "notify-attributes-natural-language" to
represent "attributes-natural-language" in subscription requests and objects
to distinguish it from the request's "attributes-natural-language"
attribute.

The next step will be to update the full specification. We will produce the
following separate documents:
IPP Notification Specification
IPP Notification Delivery Methods - separate (short) document for
each method
IPP collection attribute syntax - used by the Notification
Specification
IPP Job Progress Attributes - new Job attributes for monitoring job
progress and used by the 'job-progress' event.
The Set-Job-Attributes operation will continue to be document in the
Additional Operations (Set 2) specification (formerly called Administrative
operations), since the Set-Job-Attributes operation is useful for modifying
more than just notification Job attributes.
