In RFC 2597 - AF PHB group, Juha has generalized it with N AF classes and
M Drop precedences in each.

4 AF Classes with 3 Drop Precedences have been recommended for general use
and the DSCP defined for them. More AF classes or levels of drop
precedence may be defined for local use i.e within the diffserv domain of
the provider, however at the edges it must use the defined 4 AF Classes
with 3 DPs only.
