Because IE6 will create wrong DOM for those elements, e.g.

<section>
  <p>...</p>
</section>

is represented as

<section/>
<p>...</p>
<section/>

So you can't effectively apply CSS on section container.

I don't see how this can help. You can scale images on canvas, but
canvas has its own dimension. You can set those directly on img element.
Also placing image as canvas + JS to rendering is really bad design if
you can use img directly.

This doesn't have anything to do with TC. TC just manages DocBook
markup. DocBook stylesheets are maintained by informal group of developers.

What's real advantage of using:

<article> + above show funky Javascript

over completely static and proven:

<div class="article">

? To my knowledge there is no single real advantage except you can say
that you are cool because you are using new HTML5 markup. IMHO this is
not enough justification for changing stylesheets output. There are much
important features and bugs in queue.
