There are also some problems with the DNSSEC protocol. For example the lack of a clear error code to indicate a validation failure is a serious shortcoming and some corner case replay attacks are possible. Clients can't easily tell the difference between a SERVFAIL because of a DNSSEC validation problem or some other reason.
