Kevin,

Making the app protocol and address families object identifiers
solves the problem of adding new app protocols and address families
after the MIB has been published. If they are represented
by numbers, then each will have to be approved (so there is no
duplication) and added to the MIB. If they are object identifiers,
they can be defined within a private MIB to ensure no duplication.

I agree that this is a cumbersome way of doing it, especially when
these appear as an index, but it allows for the most flexibility.
