Thanks Ira,
One minor note, instead of deleting accounting it now
says Accounting Attributes (instead of metrics)
and it just says:
The PSI shall support accounting metrics and attributes as
defined in a named version of the PWG Semantic model.

Subject: PS> PSI Reqs revised Security/Discovery sections
Hi folks, Tuesday (21 October
2003)
Below are complete rewrite replacements for the former sections:
- 5.4 Security
- 6.1 Print Service Discovery Requirements
Note that at our face-to-face review two weeks ago, we decided to
DELETE
entirely the former sections:
- 5.5 Accounting Metrics - to be DELETED
- 6 Other Considerations - to be DELETED
Thus, the two replacement sections now are:
- 5.4 Security
- 5.5 Discovery
Cheers,

5.4 Security
The PSI shall select one or more existing standard end-to-end security
protocols. The selected PSI security protocol(s) shall be specified as
optional to use for all PSI implementations, but mandatory to support
for all PSI implementations. The selected PSI security protocol(s)
shall support:
(1) Client Authentication - protection from PSI service access by any
unauthenticated client system or process.
(2) Server Authentication - protection from PSI service offering by any
unauthenticated server system or process.
(3) Data Integrity - protection from PSI message insertion, message
deletion, or message modification by any intermediate system.
(4) Data Privacy - protection from PSI message content disclosure to
any intermediate system.
The PSI shall NOT specify or encourage the use of any hop-by-hop (link
or network layer) security protocols, because they do not offer any
end-to-end (application, session, or transport layer) security.
5.5 Discovery
The PSI should select and recommend one or more existing standard
discovery protocols. The selected PSI disovery protocol(s) should
support:
(1) Service advertising
(2) Service type discovery
(3) Service capabilities discovery
(4) Device advertising
(5) Device type discovery
(6) Device capabilities discovery
