The router should see at most one ASPA from a cache for a
particular Customer Autonomous System Number active at any
time. As a number of conditions in the global RPKI may
present multiple valid ASPA RPKI records for a single customer
to a particular RP cache, this places a burden on the cache to
form the union of multiple ASPA records it has received from
the global RPKI into one ASPA PDU.
