Question Command Class / Parameter ID mismatch handling

What is the consensus on how a responder should handle and respond to a Command Class CC data and Parameter ID PID data mismatch. As an example if the CC data is DISCOVERY_COMMAND and the PID data is DEVICE_INFO assuming it is not a broadcast address should the responder ignore the command and do nothing or respond with a NACK and if a NACK response is called for should the NACK reason code be NR_UNKNOWN_PID meaning that the CC Command Class takes precendence over the PID Parameter ID or should the NACK reason code be NR_UNSUPPORTED_COMMAND_CLASS which would mean that the PID Parameter ID takes precedence over the CC Command Class.
I am assuming that if the address is a broadcast address that I should just ignore the packet and wait for a valid packet.
