Description

Was playing around for first time with index and found anomaly with IE 7. Doesn't happen on Mozilla/Chrome/Safari. It looks like IE is adding an element to DOM before the document.body.

The indices for dom elements in I/E 7

<html> = 0

<head> = 1

<body> = 3

I did some more research and updated my sample html, turns out IE is adding a <TITLE> when none exists.

The 

<title>
element is required for most doctypes, so IE is probably adding an empty one in an attempt to to turn an invalid document into a valid one.

Also, since the document uses self-closing tags this must be some variation of XHTML, but there is no doctype so IE is parsing it in quirks mode.
