Hmm, very interesting, but with the JSR 303 coming, wouldn't be better wait for it? JSF2 will have built'n support for it, even JPA2 will have-it as far i know.
I don't understand the motivation for this project. It's duplicating the effort of JSR-303 (Bean Validation) and putting itself up against the new coming in Bean Validator in JSF 2. I find it counter-productive to contend within the same community and somewhat hostile to be posting the news here since we are the ones working on improving the Hibenrate Validator/Bean Validator integration with JSF.
