I agree that the current I-D breaks SMI, strictly speaking, BUT
any future I-D MUST be backward compatible with RFC 1759
'over-the-wire'. Removing the (redundant) index object from
the trap binding is NOT backward compatible. It's note
the IETF's SMI rules that are paramount here. It's the
PWG's commitment to backward compatible extensions to
RFC 1759 only in Printer MIB v2.
