struts validator

Hi,

Is there any documentation or examples of how to use the struts
validator framework within keel? Since Keel has only one action mapping
and form-bean for the model action it seems like maybe the validator
framework isn't a viable option unless I abandon the use of models and
write my own struts actions. Is this the case or is there a way to
configure the validator to work with keel models?

If the struts validator plug-in isn't supported well within keel I'm
considering creating a keel validation service with the turbine-fulcrum
project's intake service. 

Thanks,
Lou
