title: Struts2 xml validation on HTML tags
body: <p>We are currently migrating our application from struts1 to struts2.</p>
  
  <p>Our forms are composed with HTML tags and we are not using struts2 tags.
  The forms are displayed without any problem.
  But when we add the struts xml validation files the forms are empty (no input is displayed).</p>
  
  <p>Is there a way to use the struts2 xml validation on HTML tags ?</p>
