title: Polyfill HTML5 form attribute (for input fields)
body: <p>This is the markup I use:</p>
  
  <pre><code>&lt;input type="text" form="myform" name="inp1" /&gt;
  &lt;form id="myform" name="myform"&gt;
      ...        
  &lt;/form&gt;
  </code></pre>
  
  <p>Now I realized that it does not work for old IE and therefore I am searching for a HTML 5 polyfill.</p>
  
  <p>Anyone aware of a certain polyfill which covers this HTML5 feature?</p>
