Hi Tom,

Sorry this is so obscure.

The real reason is quite simple.

RFC 3805 defined two SEPARATE MIB modules:

IANA-PRINTER-MIB
- enums that can be changed and are IANA managed
  (so-called "Type 2" enums)

Printer-MIB
- enums that CANNOT be changed because IANA doesn't have them
  (so-called "Type 1" enums)
- also all the objects in the main body of the MIB (also can't be changed)

Your prtMarkerSuppliesSupplyUnitTC is in the second module.

It's just a physical impossiblity to change it without an entire
new RFC, because IANA does NOT have the source file to
this second MIB module.

Do you see?

This is very badly explained in section 2.4.1 of RFC 3805 - using the
Type 1 and Type 2 language of IPP/1.1 (RFC 2911).

Cheers,
- Ira
