> Constraints on parameters whose type is a subtype of the accepted types by the constraint are declared directly on the parameter
>    void doHarm(@NotEmpty String kittenName);
> Constrains on parameters whose type is a constrained bean needs an annotation accepting the targeted groups. It was proposed to use @Valid for such case but [recent discussions|https://hibernate.onjira.com/browse/BVAL-208?focusedCommentId=43533#comment-43533] brought that back on the drawing board.
> There are a few notions floating around @Valid
> 1. cascade validation to nested beans
> 2. translate the validation of group A from the owning bean to validation of the group B on the nested bean (see BVAL-208)
> 3. define the group to validate in a method level validation
> About 3., I wonder if this should be part of Bean Validation or be part of the interception framework. In other words:
> * should it be an annotation provided / proposed by Bean Validation and recognized by interception techs like CDI, @Inject, Spring, AspectJ etc
> * should each interception tech provide its own annotation to specify the targeted group(s)
