The text states at 6.4.3.3:
"The order of the returned values with the same timestamp should be from the most recent to oldest modification timestamp, if startTime is less than or equal to endTime. If endTime is less than startTime, then the order of the returned values will be from the oldest modification timestamp to the most recent."

However, this contradicts the expected result of 011 Lab CTT at https://opcfoundation-onlineapplications.org/profilereporting-v1.03/testcases/Server/HistoricalAccessModifiedValues.html which says that "The server returns the data in chronological order; and the values for each timestamp are also in chronological order."

If a faithful implementation to the text is followed, the timestamps will be in chronological order (oldest to newest, i.e startTime <= endTime) but all modifications for a timestamp will be in reverse chronological order (newest to oldest modificationTime).

Can some clarification be provided?
