This field is used to request a message that has been further sub-divided into
alternative data structures. When requesting messages with alternative data
structures, this message subsection identifier must be provided, so that the correct
sub-division of the message data is provided. If the message structure is not sub-
divided into different structures, this field should be null.
This identifies the second distant AIS being interrogated. Only one message may
be requested from the second AIS. The MMSI of the second AIS may be the s
MMSI as the first AIS. This technique can be used to request a third message
from station-1.
