title: Do HTML5 custom data attributes “work” in IE 6?
body: <p>Custom data attributes: <a href="http://dev.w3.org/html5/spec/Overview.html#embedding-custom-non-visible-data" rel="noreferrer">http://dev.w3.org/html5/spec/Overview.html#embedding-custom-non-visible-data</a></p>
  
  <p>When I say “work”, I mean, if I’ve got HTML like this:</p>
  
  <pre><code>&lt;div id="geoff" data-geoff="geoff de geoff"&gt;
  </code></pre>
  
  <p>will the following JavaScript:</p>
  
  <pre><code>var geoff = document.getElementById('geoff');
  alert(geoff.dataGeoff);
  </code></pre>
  
  <p>produce, in IE 6, an alert with “geoff de geoff” in it?</p>
