The ReadAnnotationDataDetails structure reads the Annotaion Data from the history database for the specified timestamps for one or more HistoricalDataNodes .

The order of the Annotations Data returned shall match the order of the timestamps supplied in the request.

If Annotation Data is not supported for a HistoricalDataNode then the StatusCode shall be Bad_HistoryOperationUnsupported.

If the read request is taking a long time to calculate then the Server may return zero results with a ContinuationPoint that allows the Server to resume the calculation on the next Client HistoryRead call.
