    Description

      Daffodil has a layer transform for AIS format's payload armoring.

      The tests of this use a complete AIS record with a final checksum field.

      However, this checksum is not recalculated. 

      We should enhance this schema with a checksum calculation using the new features implemented for DAFFODIL-2221

      This layer, and the AIS encoding layer should become pluggable (per DAFFODIL-1927), and be implemented as part of an AIS DFDL schema project (on github) which includes the test/example schema for a complete AIS message, as well as the Scala code for the 2 layers needed. One for the payload armoring, another one for the checksum.
