plinss: I've been looking at: <ul><li>1</li><li>2</li><ul><li>a</li><li>b</li></ul>

currently the html5 spec appears to dislike this content.

(err, there should be two `</ul>`s at the end)

someone suggested that it should be rewritten as:

<ul><li>1</li><li>2<ul><li>a</li><li>b</li></ul></li></ul>

but at least for the sample content I'm looking at, the a&b items are not actually interested in being children of 2, they just are somehow "less important" than 1&2

an alternative structure for that is: <ul><li>1</li><li>2</li><li><ul><li>a</li><li>b</li></ul></li></ul>

but at least /sometimes/ that renders with two bullets on the `a` line (and only one on the `b` line) -- it looks really ugly (it's easy to trigger this rendering when using github's markdown language)

in this case, I think the more correct content model is probably: <ul><li><ul><li>1</li><li>2</li></ul></li><li><ul><li>a</li><li>b</li></ul></li></ul> -- in that it shows that 1&2 are not related to a&b, but the rendering of that would just double the number of screwy bullets showing up
