Oops... malfunctioning brain :-) How about

   /**
     Used for QS_DYNAMIC_RANGE, i.e., "Range checked for each record".
     Used by optimizer tracing to decide whether or not dynamic range
     analysis for this select has been traced already. If optimizer
     trace option DYNAMIC_RANGE is enabled, range analysis will be
     traced with different ranges for every record to the left of this
     table in the join. If disabled, range analysis will only be traced
     for the first range.
