title: Custom attribute not working in IE10
body: <p>I have a input text type</p>
  
  <pre><code>&lt;input type="text" name="firstNameInd" style="width:200px;" required="true" maxlength="100" /&gt;
  </code></pre>
  
  <p>"required" is a custom attribute which i access using javascript.</p>
  
  <p>This is working fine in IE 7 and 8, but not in IE10 it shows required="". </p>
  
  <p>Might be it was due to that required is an attribute in HTML5.</p>
  
  <p>Can any one suggest what to do?</p>
