CCCC.4.6 Selection Status

This is used to flag the preferred value when multiple instances of the same measurement are recorded in the SR object. Using this to communicate the value preferred by the operator or the Ultrasound System is very useful for receivers that lack the logic to make a selection themselves. In cases where there is no need or value in sending multiple instances of the same measurement, the issue can be avoided by only sending a single instance of any given measurement in the SR object.
