Re: [CF-metadata] Platform Heave
Jim's definitions work for me. I don't think we need to state the roll, pitch and yaw need to be in angles. The Standard Name table conical units indicate that. As for the order of the definitions I don't think we have a standard that has been strictly enforced, and no matter what order we put them in someone will prefer a different order.
