There is, as Joe Abley mentioned, a definition of authorization
in routing registries. But the definition of "certified" still
becomes problematic/controverial at times. crypt-pw? pgpkey? X.509
certs? singly rooted PKI? etc.

Another problem is the scope of "dynamic" - would daily changes to the
IRR database from which you construct a filter list nightly satisfy as
being "dynamic" enough?
