What do the messages on seat reservation displays mean on-board CrossCountry services?

An explanation can be found below of each of the messages you might see on CrossCountry on-board seat reservation displays:

• Seats which are available and cannot be booked into during the train's journey will show as 'Available' within the seat reservation displays. Unless the train is fully reserved before the day of departure, there will always be a section of the train which is unreservable and available for customers without a seat reservation.
• Seats which can be reserved during the train's journey will display the message 'Available, but reservable en-route (origin) to (destination), e.g. 'Available, but reservable en-route Bournemouth to Manchester'. This means that the seat is currently available but may be reserved by other customers during the train's journey. 
• Reserved seats will display the journey information for the reservation, for example 'Cheltenham to Wolverhampton' or 'Reserved from Stafford'.
