If you google an XLs warning system you can find a pdf of it. The one I found has a "no takeoff" annunciator that does not include the parking brake. Might not be accurate but if it is and there have been previous incidents where partial application of the brake was involved I would think NTSB and/or Cessna would make it a point to insure crews checked the parking brake knob to be fully in/off before takeoff.
