                 Key: HV-549
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-549
             Project: Hibernate Validator
          Issue Type: New Feature
            Reporter: George Sapountzis


ValidatorImpl currently supports methods for validating bean properties / method parameters. Looking from the outside, I don't see a strong reason for using bean properties / method parameters other than that these elements are annotation placeholders.

Using TypeLiteral/AnnotationLiteral helper classes it seems possible to construct all the necessary metadata for a validation point programmatically. So, I propose to add a generic method where the annotations/type are passed by the user. The passed value need not be a bean, it could be a *primitive* value. The resulting set of constraint violations will just have a null root bean / method.

Hope you consider this a valid case and add such a method, or advise on an alternative way to achieve the same functionality. I'd like to do this without writing straw beans/methods and introspecting them just for the sake of adapting to the API. I am not able to find my way around to achieving this currently.
