/**
 * A validator that supports both the API of Symfony < 2.5 and Symfony 2.5+.
 *
 * This class is incompatible with PHP versions < 5.3.9, because it implements
 * two different interfaces specifying the same method validate():
 *
 *   - {@link \Symfony\Component\Validator\ValidatorInterface}
 *   - {@link \Symfony\Component\Validator\Validator\ValidatorInterface}
 *
 * In PHP versions prior to 5.3.9, either use {@link RecursiveValidator} or the
 * deprecated class {@link \Symfony\Component\Validator\Validator} instead.
 *
 * @since  2.5
 * @author Bernhard Schussek <[e-mail]>
 *
 * @see \Symfony\Component\Validator\ValidatorInterface
 * @see \Symfony\Component\Validator\Validator\ValidatorInterface
 *
 * @deprecated Implemented for backwards compatibility with Symfony < 2.5.
 *             To be removed in Symfony 3.0.
