How can I generate a TOC in correctly nested ordered XHTML list elements
from the flat heading structure in XHTML 1.0?
I am only interested in correctly nested ordered lists as output, like this:

<ol>
	<li>
		<ol>
			<li/>
		</ol>	
	</li>
	<li/>
</ol>

XSLT 2.0 will do. I have no problems with the first level.
