Unused.
User-assigned priority level (0 to 7) of the reference associated with Profile 3 while
that reference is the active reference. The numeric value of the promoted priority
must be less than or equal to the numeric value of the selection priority.
User-assigned priority level (0 to 7) of the reference associated with Profile 3, which
ranks that reference relative to the others.
