So from that it appears the Azure batch message format is a 'first message annotations' included in the 'agregating message', followed by one or more Data body sections to carry the other individual messages, with each body section carrying the encoded bytes of an encoded full amqp message (and all its encoded sections) from the batch...with all those bytes then sent into a single delivery with the special message-format code to indicate its an 'azure batch message' rather than a normal/default AMQP 1.0 message encoding (though, the components used in the aggregating message are actually a regular message encoding in themselves).
As I said In my other reply, I dont know if the C++ binding can actually do that, its a higher level client binding implemented over the C bits (which should be able to) so I dont know that it actually exposes defining message-format or the ability to pass the raw delivery-bytes rather than messages as its rare an application would use those (whereas the java bits referenced here are all low level engine bits, used within the higher level Azure client, which again hides all that).
