title: EL function not found in validator attribute
body: <p>El function cannot be found using within validator attribute, which is dependent on dynamic or repeated values?</p>
  
  <pre><code>Function 'el:min' not found
  </code></pre>
  
  <pre class="lang-html prettyprint-override"><code>#{el:min(a + b, c)}
  &lt;f:validateLongRange maximum="#{el:min(foo.bar, 10)}"/&gt;
  </code></pre>
  
  <p>Just printing out the value is working where it is not working in the validator.</p>
