It is my understanding that 1SetOf is unordered. But rfc2911 states
"Sets are normally unordered. However each attribute description of
this type may specify that the values MUST be in a certain order for
that attribute." I assume that the description will detail the ordering
including the mapping to the Printer MIB and any ordering relationship
between attributes.

Ira,
I'm working on getting this text into a new rev of the JPS3
specification. Some comments below...

(3) prtMarkerSuppliesColorantIndex is omitted in

because it is redundant with prtMarkerColorantIndex for the rows

include colorant information.
Do we even need the colorantIndex from the prtMarkerColorant table?
Seems like unnecessary information that will never get used in this
composite view of the two tables...
Same for Index - we implicitly already have it (1setOf is ordered) so
why include it?
MaxCapacity should be REQUIRED since otherwise how do you interpret
Level?
Finally, I would make at least the colorant Value conditionally
required, otherwise the data can't be represented properly in UI.
