Hi, Right - ASN.1 doesn't allow discontinuous integer ranges. The DESCRIPTION clause of this textual convention could disallow the length of '1', but it's not important to do, I think. With respect to max length of 60, the public MIBs that I'm aware of often use 63 octets and the rest use a longer max length (except for the admittedly flawed legacy objects in Printer MIB v2, RFC 3805 - I tried to fix them before we published RFC 3805, but got shot down by my co-editors).

I wouldn't even bother with this change. -- John Cowan cowan@xxxxxxxx http://ccil.org/~cowan Rather than making ill-conceived suggestions for improvement based on uninformed guesses about established conventions in a field of study with which familiarity is limited, it is sometimes better to stick to merely observing the usage and listening to the explanations offered, inserting only questions as needed to fill in gaps in understanding. --Peter Constable _______________________________________________ Ltru mailing list Ltru@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ltru -- No virus found in this outgoing message.
