"Discarding the RRset before the TTL has expired" is not a protocol
violation: there are many legitimate reasons why a resolver might do
so (lack of memory, for instance). The text in the draft referred to
"hanging onto the RRset after the TTL has expired" (hence the
reference to "very short TTL") which *is* a protocol violation.
