The following was the original "Universal IE6" stylesheet inclusion method:

	<!--[if ! lte IE 6]><!--><link rel="stylesheet" href="NON_IE6_STYLESHEET" media="screen, projection"><!--<![endif]--> 
	<!--[if lte IE 6]><link rel="stylesheet" href="http://universal-ie6-css.googlecode.com/files/ie6.0.3.css" media="screen, projection"><![endif]--> 
	

I tried the following lesser-known "downlevel revealed" conditional comment. ("Downlevel revealed" conditional comments treat non-IE browsers as "downlevel", ironically enough. The name comes from the fact that they are also revealed in IE4 and lower.)


	<![if ! lte IE 6]><link rel="stylesheet" href="NON_IE6_STYLESHEET" media="screen, projection"><![endif]> 
	<!--[if lte IE 6]><link rel="stylesheet" href="http://universal-ie6-css.googlecode.com/files/ie6.0.3.css" media="screen, projection"><![endif]-->
