2.2 Message Syntax
For all non-IDL packet definitions in this section, this specification uses both [C706] definition style and a packet diagram to facilitate understanding of how the [C706] specification is extended. In all non-IDL packet definitions in this section, bit ordering rules are the same as what is specified in [C706], unless explicitly stated otherwise.
Unless otherwise specified, all padding octets can be set to any arbitrary value when sent and MUST be ignored by the receiver.
