Hi Karyn,
rfc2317 (which defines classless reverse) doesn't break it (although it is
not explicit on this point) - rfc1912 only requires that the FQHN returned
from a PTR record matches an A record. Going the other way - finding the
PTR record itself via a CNAME - is not a violation.
As an aside, rfc2137 unfortunately *does* allow the final delegate to
pollute external resolvers with incorrect SOA records for the
octet-boundary parent zone. That's just a typical DNS hazard, of course.
