The router MUST see at most one ASPA for a given AFI 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.
