Because of domain name compression.  An RR containing compressed names
will be silently corrupted if it is transmitted as a mere block of
bits.  There is also a couple of other issues like the downcasing of
embedded domain names currently required for DNSSEC canonicalization.

draft-ietf-dnsext-unknown-rrs-00.txt is an attempt to address this.
