The posters above seemed to want a record of all the intermediate stages and of the order in which they were set. The xmp won't supply the goods because it shows only the settings at a given moment, usually the final moment before export or transfer to another application - or discouraged abandonment. I often spend several minutes searching for the best balance between
"Exposure", Highlights and White Point or between Sharpening, Clarity and NR
Moreover, the settings are listed in a fixed order, which may or may not be the same as the user's plan of attack.
