NOTE 1 This is used to bind the contents of the ACA and ACS sentences together. If
provided by the AIS, the ACS sentence shall immediately follow the related ACA
sentence, and both sentences shall contain the same sequence number. The AIS
generating ACA and ACS sentences shall increment the sequence number by one
each time an ACA/ACS pair is created. After "9" is used, the sequence number
process shall begin again from "0". If the sequence numbers do not match, th
information contained in an ACS sentence is not related to the information in an
ACA sentence. The ACS sentence may be used to respond to an "ACA Query-
