title: What's IE take on HTMLDocument and HTMLElement
body: <p>Within javascript's scope, referring  to <a href="https://developer.mozilla.org/en/DOM/HTMLDocument"><code>HTMLDocument</code></a> or <a href="https://developer.mozilla.org/en/DOM/HTMLElement"><code>HTMLElement</code></a> raises error on IE8.</p>
  
  <p>The error I get is "HTMLElement is undefined".</p>
  
  <p>What is the way to have JS interacting with native DOM object of this browser?</p>
