At ISE we have the full detail of the instrument in all messages. We found that our customers were coding to this message for the first time and were quite flexible. Some of our customers asked if we could remove the instrument data from the incremental messages to make it more efficient. We are ain about to implement this change into production, but so far it has been well recieved and will reduce the bandwidth significantly.
