That may need a little more explanation: IE does not distinguish
between ID and name attributes when using getElementById, it treats
them all as IDs. Given:
<div><input name="sally"></div>
<div id="sally"></div>
Then in IE, document.getElementById('sally') will return a reference to
the input, not the div.
