@evan However, I didn’t understand your statement about all properties in any AP document. I am thinking the reverse chrono ordering applies to Object ordering in an OrderedCollection. The property or properties used for sorting keys aren’t specified. Also from Section 5, “What property is used to determine the reverse chronological order is intentionally left as an implementation detail.”
