title: How many ways there are to declare variables in facelets?
body: <p>I noticed that c:set does not work well used inside "include of include of include", as important notice facelets documentation does't recommend it too.</p>
  
  <p>Now I am using ui:param inside ui:include, but it is a bit dispersive when no attached notes about params comes with the include, is there something other way to declare "global vars"?</p>
