58  * A constraint has a name and a value and an optional message.
59  * The name/value pair will have meaning to a Validator and the
60  * message will serve as an error message in the event the Validator
61  * determines the constraint is violated.
62  * example:
63  * name="maxLength"
64  * value="255"
65  * message="Value cannot be longer than 255 characters."
