RULES 8.3.4.1 (Message Receiver)
================================
* If the full Submessage header cannot be read, the rest of the Message is considered invalid.
* If submessageLength field is invalid, the rest of the Message is invalid.
* A Submessage with an unknown SubmessageId must be ignored and parsing must continue with the next Submessage.
* The receiver of a Submessage should ignore unknown flags.
* A valid submessageLength field must always be used to find the next Submessage.
* A known but invalid Submessage invalidates the rest of the Message.
