Looks to me like:

proof of allocation:
S(withRIRkey, Prefix_p_key, prefix_p)
             as Steve pointed out, there could be two of these,
             one with CA bit set for use in suballocation
             and one without the CA bit set for use in routing

proof of identity
S(withRIRkey, AS_A_key, AS_A)
or
S(withwebofttrustkeys, AS_A_key, AS_A)
             maybe Randy is saying this is two steps, not an "OR"

proof of origination authorization:
S(withPrefix_p_key, authr_origin_AS_#, prefix_p)

proof of origination authentication:
S(withAS_A_key, (AS_A,prefix_p)update)
     could be S(withAS_A_key, (AS_A,prefix_p)||proofoforiginationauthr)

The binding between the proof of origination authorization and
the proof of origination authentication is that the AS_A in the proof
of identity mapping AS_A to the AS_A_key must be the same as 
the authr_origin_AS_# in the proof of origination authorization.

[Future complication of this would have to decide what to do with ISPs
that own more than one AS #. (make "authr_origin_AS_#" a list?)]
