From the draft http://tools.ietf.org/html/draft-barwood-dnsop-ds-publish-01 A new resource record type is preferred to using flags in the DNSKEY RRset. It allows the DS to be published without revealing the public key, delaying the time at which an attacker can start cryptanalysis; the size of the DNSKEY RRset is not changed, which avoids potential transport problems with large responses; and it allows arbitrary DS records to be published which may have no corresponding DNSKEY, which might be useful in future for defining transport parameters.
