I thought we had tried to remove this distinction... but I see it is
still part of the PrtSubUnitStatueTC. So a sub-unit can be Available
and Busy or Available and Active. Does anyone know what the distinction is?

In general, if I'm building a printer with 3 input trays and the printer
is printing... picking from tray 1... what should be the status or each
tray (subuint)?

Tray 1 - Available and Active
Tray 2 - Available and Idle
Tray 3 - Available and Idle

Is this the perceived design goal? What if a printer is less capable of
detecting this granularity and, when any printing is going on all 3 trays
reflect Available and Active or Available and Busy? Is this considered to
be a correct implementation?
