/**
* Variant of JSR-303's {@link javax.validation.Valid}, supporting the
* specification of validation groups. Designed for convenient use with
* Spring's JSR-303 support but not JSR-303 specific.
*
* Can be used e.g. with Spring MVC handler methods arguments.
* Supported through {@link org.springframework.validation.SmartValidator}'s
* validation hint concept, with validation group classes acting as hint objects.
*
*
Can also be used with method level validation, indicating that a specific
* class is supposed to be validated at the method level (acting as a pointcut
* for the corresponding validation interceptor), but also optionally specifying
* the validation groups for method-level validation in the annotated class.
* Applying this annotation at the method level allows for overriding the
* validation groups for a specific method but does not serve as a pointcut;
* a class-level annotation is nevertheless necessary to trigger method validation
* for a specific bean to begin with. Can also be used as a meta-annotation on a
* custom stereotype annotation or a custom group-specific validated annotation.

Other {@link org.springframework.validation.SmartValidator} implementations may
