I sort of fudged on the below. The upside is that it should be pretty
forgiving now: you can set all kinds of strings as your :html-doctype,
and it will do a reasonably good job of guessing how to handle it.

Barring actual bugs or poor design decisions, what's left to do is:

1. Make sure that inlined script and style chunks are escaped correctly,
I seem to remember reading that the commenting/escaping syntax for these
chunks varies according to html flavor.

2. I'd like to add the possibility to put an arbitrary :html-container
attribute on HTML elements, so that things that would have been wrapped
in "div"s can be wrapped in "article", "section", "nav", and so on and
so forth.

Rick Frankel kindly provided a test file for this, which I've modified
below:

#+BEGIN_SRC emacs-lisp
#+TITLE:  HTML 5 Test
#+DATE:  {{{modification-time(%Y-%m-%d)}}}
#+HTML_DOCTYPE: html5
#+BIND: org-html-divs ((preamble "header" "preamble") (content "section" 
"content") (postamble "footer" "postamble"))
*  Org HTML5 Test
ok? This should be a paragraph with a \\
line break in it. I think
* How about a table
| col1 | col2 |
|------+------|
| a    |    1 |
| b    |    2 |
Tables can't have attributes in HTML5.
* And a list
- a
- b
- c
* And an image
[[file:1356810947473.jpg]]
* A definiton list
#+ATTR_HTML: :options html-container article
- a :: foo
- b :: bar
#+END_SRC

Please break! I'll provide a properly-written patch when we've sorted it out.
