> Here is a summary of the changes from since 971107 (the rev version is
> against 971101) which was the doc issued just prior to the WG final
> call.
>
> 1. Added a new Introduction that gives a better roadmap of not only
> the
> model document, but all of the IPP documents.
>
> 2. Split Get-Attributes into Get-Job-Attributes and
> Get-Printer-Attributes
>
> 3. Added a new MANDATORY Request ID to each Request and Response
>
> 4. Clarified the description of each of the attribute groups
>
> 5. Added length constraints for all 'text' and 'name' attribute.
> Overall,
> the MAX for 'text' and 'name' went from 4096 to 1024
>
> 6. Removed all references to HTTP/1.1 (except for referencing IPP-PRO
> and
> examples)
>
> 7. Made the target attribute ("printer-uri" for Printer etc) a
> MANDATORY
> operation attribute
>
> 8. Added -default and generated- and -configured as decided in LA
>
> 9. Clarified natural language acceptance rules and Natural Language
> Override rules
>
> 10. Client SHOULD NOT send invalid combo of charset and natural
> language
> (Printer will accept)
>
> 11. Clarified that "status-message" is an OPTIONAL operation attribute
>
> 12. Generally made strict rules on what a sender sends and forgiving
> rules
> on what a receiver receives.
>
> 13. Removed 3.1.5 and moved it all to section 8
>
> 14. Made version rules more practical
>
> 15. Encoding rules and order of first bytes in application/ipp is NOT
> ALLOWED to change (this is op, version, and request id). This will
> remain
> consistent across all versions
>
> 16. Made compression, job-k-octets, job-media-sheets, and
> job-impressions
> operation attributes. Aligned these with Job MIB
>
> 17. Clarified Unsupported Attributes group in responses and made it
> possible for ALL operations to return unsupported attributes
>
> 18. Added 'no-value' out-of-band value and made better rules for
> 'unknown'

>
> 23. Removed '0' for n-up
>
> 24. "media-ready" is OPTIONAL
>
> 25. Added an ALL new security section (TLS vs non-TLS, Printers
> OPTOINALLY
> support TLS, clients SHOULD support TLS, added "printer-tls-uri",
> etc.)
>
> 26. Defined categories for text and name attributes (catagorized by
> source
> of value client vs Printer vs operator vs admin vs vendor etc) Placed
> name
> and text attributes in each catagory. Gave better rules for which
> supported
> and which defaults apply to which categories
>
> 27. Fixed up rules for 'requeting-user-name" vs authentication service
> name
> and which is which and who each applies to "job-originating-user"
>
> 28. Provided a TLS ciphersuite profile for IPP
>
> 29. Added 'not-accepting-jobs' error code
>
> 30. All new 15.3 and 15.4 sections on suggested steps for validating
> operations
