To the readers of this mail: I would like to urge that the database structure of BIND MUST NOT define the semantics of DNS. Breaking the RFC1034 model which assures the uniqueness of DNS RR integrity will significantly hamper the fundamental security of the current non-cryptographic DNS, which is still heavily dependent of the uniqueness of AXFR-transferred data. If you all disapprove A6, please do NOT approve such an idea, again. // Kenji Rikitake
