15.1Changes to the March 1, 2000 version to make the March 8, 2000 15.1Changes to the March 21, 2000 version to make the March 23, 2000
version
The following changes have been made to the March 21, 2000 version to
make the March 23, 2000 version as a result of the IPP WG telecons and
mailing list discussion:
1.Changed the name of the 'custom' out-of-band value to 'admin-define'.
2.Tightened up the spec for 'admin-define' so that it cannot be used
returned in a Get-Printer-Attributes response to allow users to
submit arbitrary values in a Job Creation operation. If that
functionality is needed, it will have to be done with another out of
band value.
3.Clarified that the 'admin-define' out-of-band value is only intended
to be used with "xxx-supported" attributes in a Get-Printer-
Supported-Values response that are defined to include the 'name'
attribute syntax. If other documents extend this usage, they MUST
define for which attributes and operations.
Expires: September 23, 2000
4.Added the definitions of the xri-uri-scheme-supported (1setOf
uriScheme), xri-authentication-supported (1setOf type2 keyword), and
xri-security-supported (1setOf type2 keyword) READ-ONLY Printer
attributes that were only referred to. Also made them returnable
only in Get-Printer-Attributes, not Get-Printer-Supported-Values,
since they are READ-ONLY and the administrator cannot change them.
5.Clarified that the few "xxx-supported" attributes that are single
valued, are made 1setOf X in the Get-Printer-Supported-Values so that
the implementation can indicate what possible values can be set.
6.Required the client to have administrator access rights in order to
use the Get-Printer-Supported-Values operation, since its purpose is
for administrators to use before doing a Set-Printer-Attributes
operation.
7.Clarified that if an implementation supports setting arbitrary names
in a Set-Printer-Attributes request, then it MUST support the 'admin-
define' out-of-band value in the Get-Printer-Supported-Values
response.
8.Copied the validation rules from the Implementer's Guide into
Appendix A, since the IIG is not a standards track document. Still
refer to the IIG for additional non-normative explanation.
15.2Changes to the March 8, 2000 version to make the March 21, 2000
version
The following changes have been made to the March 8, 2000 version to
make the March 21, 2000 version as a result of the IPP WG telecons and
mailing list discussion:
9.Changed the name of the 'any-value' out-of-band value to 'custom'.
Removed the idea of encoding the attribute syntax that the 'custom'
out-of-band value goes with. Required the value length to be zero.
Instead, the spec for the attribute or attribute syntax defines
whether or not the 'custom' out-of-band value can be used.
10. Clarified that the 'custom' out-of-band value can be used in
combination with other values of an "xxx-supported" Printer
attribute.
11. Clarified that an implementation is not prevented from supporting
some 'name' attribute values for "xxx-supported" out-of-the-box, if
desired. But these values would be returned in a Get-Printer-
Supported-Values response, such like keywords are.

indicated in this Appendix as "any xxx", it can make the value be read- indicated in this Appendix as "any xxx", it can make the value be not-

supported" is "false" and MUST be read-only. Otherwise an administrator
could set it to "true" because the value can have "any boolean"
