[IPP] Working on IPP Everywhere umbrella spec, some thoughts...

All,

As I am getting the rest of the IPP Everywhere spec together, it occurs to me that there are two logical categories of IPP printers we may want to use from a client:

1. A standalone personal/workgroup printer that prints (and accepts) one job at a time (basically IPP/2.0)
2. A managed printer/print service that prints (and accepts) multiple jobs at a time (IPP/2.1 or IPP/2.2)

Now, we could define these as separate conformance levels for IPP Everywhere, *or* we could have IPP Everywhere use the protocol versions defined in IPP/2.0 SE as the basis for IPP Everywhere's different conformance levels.

Quick outline:

IPP/2.0: Add required JPS3 attributes and operations, Cancel-My-Jobs and media-col-database from JPS2, DNS-SD for discovery, and PWG Raster as the required document format.

IPP/2.1: Add required JPS3 attributes and operations, Cancel-My-Jobs, Cancel-Jobs, and media-col-database from JPS2, DNS-SD, LDAP, and SLP for discovery, and PWG Raster and PDF as the required document formats.

IPP/2.2: Add required JPS3 attributes and operations, DNS-SD, LDAP, and SLP for discovery, and PWG Raster and PDF as the required document formats.

Thoughts?
