> Currently, there are two core-supported methods for specifying the validators to be applied to a particular form field: the @Validator annotation, and the validate attribute.  Tapestry supports, however, specifying constraints to a specific validator in the .properties file. For instance: 
>   <t:textfield t:id="someField" validate="regexp">
> Could have an entry in the .properties file such as:
>   someField-regexp=^\d+$
>   someField-regexp-message=You must input a number for someField
> What would be equally nice is to be able to specify the actually regexp validator as a constraint in the .properties file:
>   someField-validators=regexp
> Or
>   someField-validators=required,regexp
> This would be helpful for using, eg, BeanEditForm, where you might want to specify the constraints for a large number of fields, don't want to provide parameters for each of those fields, and you don't have access to the source to add @Validator to each of the properties.
> This will probably take the form of a new ValidationConstraintGenerator, but there may be some additional "plumbing" involved to get access to the containing page/component's message catalog.
