Description: Section 5.3 [6.3]: The three parts of the messages are listed and the last sentence says that "The following sections describe the format of each part of the message", but there are 4 sub-sections in 5.3 [6.3], with the first section NOT describing one of the three parts of the messages. I suggest to strike that last sentence and just put references to the sections in the list items for each of the three messages.
