[IPP] "Get-User-Supported-Values" operation?

Hi Smith,

I agree with Mike that this operation should not be added to IPP System
Service.

I question the need for this operation.

An IPP job service implementation can filter a Get-Printer-Attributes
response already based on authenticated user identity.

What new functionality would this putative operation add to IPP?

Cheers,
- Ira
