WARNING: Please refer to the actual IMO, IALA, ITU, UN, or Volpe specs over these. They do not exactly match what is in the spec. Why? I have not implemented conditional section decoding and have not validated all of the xml source definitions against actual packets. And, this directory is not the official definition of the messages!
