Hi Mike and Ira,
In my experience, Finishing options have always been one of the areas in device specific printer drivers with significant UI constraint entries. What I really like about this proposal is that it fully supports our IPP Everywhere work to significantly reduce the need for device specific drivers in that it allows the device to effectively advertise all of the current UI constraint information typically contained in a device specific driver via the IPP defined finishings-col-ready attribute.

I like "finishings-col-database".
I agree that this is necessary for practical non-expert use of pre-composed

My prototype experience shows that "pre-composed" finishing operations selected using the finishing-template member attribute are the most important/useful for non-expert UI.
Since finishings-col-ready is defined to list only those finishing operations that are available at any given time, I would like to propose adding a "finishings-col-database" attribute that holds all of the named finishing operations that are configured on a given Printer - this would provide a necessary vendor and site configuration attribute, with the finishings-col-ready attribute reflecting which finishing operations are possible based on the current subunit state.
Your comments are appreciated!
The added text is:
6.9 finishings-col-database (1setOf collection)
The RECOMMENDED "finishings-col-database" Printer attribute lists the "finishings-col" member attributes corresponding to each "finishing-template" value. For example, a Printer that supports the 'staple' value might report:
The same values SHOULD be reported in the "finishings-col-ready" Printer attribute for each finisher sub-unit that is available.
