I've updated the "Internet Printing Protocol (IPP): The Job and Printer Set
Operations" with the final issue resolutions discussed today on the IPP
telecon and mailing list:

I shortened the Abstract:

This document specifies 3 additional OPTIONAL operations for use with the
Internet Printing Protocol/1.0 (IPP) [RFC2565, RFC2566], IPP/1.1 [ipp-mod,
ipp-pro], and future versions.  The end user, operator, and administrator
Set-Job-Attributes and Set-Printer-Attributes operations are used to modify
IPP Job objects and Printer objects, respectively.  The third
Get-Printer-Supported-Values operation returns values that the IPP Printer
will accept for setting its "xxx-supported" attributes.  
Three out-of-band values are defined for use with these operations:
'delete-attribute', 'any-value', and 'not-settable', along with a
'client-error-attributes-not-settable' status code.
Two operation attributes:  "printer-message-from-operator" (text) and
"job-message-from-operator" (text) are defined to set the corresponding
IPP/1.1 Printer and Job Description attributes with the same names.
Six Printer Description attributes are defined: 
		printer-settable-attributes-supported (1setOf type2 keyword)
		job-settable-attributes-supported (1setOf type2 keyword)
		document-format-varying-attributes (1setOf type2 keyword)
		printer-message-time (integer(MIN:MAX))
		printer-message-date-time (dateTime)
		printer-xri-supported (1setOf collection)


Here are the changes:

15.1	Changes to the March 1, 2000 version to make the March 8, 2000
version
The following changes have been made to the March 1, 2000 version to make
the March 8, 2000 version as a result of the IPP WG telecons and mailing
list discussion:
1.	Added the "printer-xri-supported" (1setOf collection) attribute so
that the three parallel IPP/1.1 "printer-uri-supported",
"uri-authentication-supported", and "uri-security-supported" attributes
could be set as one atomic attribute.  Consequently, changed the three
parallel attributes to be READ-ONLY and removed the requirement that three
attributes MUST be set in a single request if the three parallel IPP/1.1
"printer-uri-supported", "uri-authentication-supported", and
"uri-security-supported" were settable.
2.	Clarified Get-Printer-Supported-Values so that if an implementation
does not support setting a settable attribute, it MUST NOT return the
attribute in the Printer Attribute group and it NEED NOT return the
attribute in the Unsupported Attributes group, same as in a
Get-Printer-Attributes response for unsupported attributes.  Same
clarification when unsupported attributes are requested.
3.	Fixed "printer-message-date-time" (dateTime) attribute to be
OPTIONAL.
4.	Added note as to why the "printer-current-time" Printer Description
attribute is settable (to fix an incorrect time or time zone).
5.	Added "xri-authentication-supported" (1setOf type2 keyword) and
"xri-security-supported" (1setOf type2 keyword) attributes to the table of
attributes that can be queried with Get-Printer-Supported-Values.  Added a
note that these two attributes are NOT queriable with
Get-Printer-Attributes, since the client queries either (1) the three
"printer-uri-supported" (1setOf uri), "uri-authentication-supported" (1setOf
type2 keyword), "uri-security-supported" (1setOf type2 keyword) attributes,
or (2) the single "printer-xri-supported" (1setOf collection) attribute.
Please send any comments to the mailing list.
Thanks,
Tom
