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.
