More interesting to me would be to pass a string literal as a discriminant. Using your example, something like this...

Type Message (Length : Positive; Text_Value : String) is record
  Text  :  String(1..Length) := Text_Value;
  -- Other components.
end record; 

This gives me an error: Discriminants must must have a discrete or access type
