title: Does spring have a validation framework module that can be used in any layer for validatons?
body: <p>For  instance, I am using JSF + custom framework developed in our company. Now I want to use  a third party validation framework that can be used as an plug-in and it should not create  any dependency what ever may be the technical stack.</p>
  
  <p>So my question is does spring provide any framework of that sort or if it's available how can I use that?</p>
  
  <p>I am expecting a validation framework something like, which is configurable through XML.</p>
