/**
* Defines the target(s) a {@link ConstraintValidator} can validate.
* <p>
* A {@code ConstraintValidator} can target the (returned) element
* annotated by the constraint, the array of parameters of a method
* or constructor (aka cross-parameter) or both.
* <p>
* If {@code @SupportedValidationTarget} is not present, the
* {@code ConstraintValidator} targets the (returned) element annotated
* by the constraint.
* <p>
* A {@code ConstraintValidator} targeting cross-parameter must accept
* {@code Object[]} (or {@code Object}) as the type of object it validates.
