when I write:
  <div><div>aa<div /></div><div>bb</div></div>
div with text bb shown inside the div with text aa
if I write 
  <div><div>aa<div></div></div><div>bb</div></div>
everything shown OK

I think it is simple bug that can be simply fixed.
I usualy meet this bug when transforms xml with
xsl and put it as innerHTML in javascript. When
xml transformed to HTML throw xsl usally recieved
first form of HTML and not seccond and it is breaks
my pages.

	</style>
</head>
<body>
	<div><div>aa<div /></div><div>bb</div></div>

If you want the page to be parsed as XML, you have to use an XML mime type.  We can't make the HTML parser treat <foo/> as self-closing without breaking lots of pages.
