/**
 * Marks an annotation as being a Bean Validation constraint.
 * <p/>
 * A given constraint annotation must be annotated by a {@code @Constraint}
 * annotation which refers to its list of constraint validation implementations.
 * <p/>
 * Each constraint annotation must host the following attributes:
 * <ul>
 * <li>{@code String message() default [...];} which should default to an error
 * message key made of the fully-qualified class name of the constraint followed by
 * {@code .message}. For example {@code "{com.acme.constraints.NotSafe.message}"}</li>
 * <li>{@code Class<?>[] groups() default {};} for user to customize the targeted
 * groups</li>
 * <li>{@code Class<? extends Payload>[] payload() default {};} for
 * extensibility purposes</li>
 * </ul>
 * <p/>
 * When building a constraint that is both generic and cross-parameter, the constraint
 * annotation must host the {@code validationAppliesTo()} property.
 * A constraint is generic if it targets the annotated element and is cross-parameter if
 * it targets the array of parameters of a method or constructor.
 * <pre>
 *     ConstraintTarget validationAppliesTo() default ConstraintTarget.IMPLICIT;
 * </pre>
 * This property allows the constraint user to choose whether the constraint
 * targets the return type of the executable or its array of parameters.
 *
 * A constraint is both generic and cross-parameter if
 * <ul>
 * <li>two kinds of {@code ConstraintValidator}s are attached to the
 * constraint, one targeting {@link ValidationTarget#ANNOTATED_ELEMENT}
 * and one targeting {@link ValidationTarget#PARAMETERS},</li>
 * <li>or if a {@code ConstraintValidator} targets both
 * {@code ANNOTATED_ELEMENT} and
 * {@code PARAMETERS}.</li>
 * </ul>
 *
 * Such dual constraints are rare. See {@link SupportedValidationTarget} for more info.
 * <p/>
 * Here is an example of constraint definition:
 * <pre>
 * &#64;Documented
 * &#64;Constraint(validatedBy = OrderNumberValidator.class)
 * &#64;Target({ METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER })
 * &#64;Retention(RUNTIME)
 * public &#64;interface OrderNumber {
 *     String message() default "{com.acme.constraint.OrderNumber.message}";
 *     Class<?>[] groups() default {};
 *     Class<? extends Payload>[] payload() default {};
 * }
 * </pre>
