I'm trying to implement Bean Validation for MyFaces, but I see something strange
in the spec (the PDF document).
Paragraph 10.4.1.4 <f:validateBean> states that the Facelets Handler class must
extend the ValidateHandler class.
Since I only see a ValidatorHandler class in the JavaDocs, I would normally
assume that's the one and there is a typo in the spec. But the Facelets codebase
contains a (deprecated) ValidateHandler class. Which one should I extend?
