Not really necessary. It's overly complex with no obvious advantage. I
guess the right question to ask is (it may have been mentioned much
earlier in the thread) -- what problem does the patch solve?

Yes, a a blog is the prototypical example -- but only the index page,
where multiple articles are concatenated into a single page.

Most likely, an org document implementing this would have the
=article=s (indvidual blog posts) at level 1, and sections below.

In the most common use, the  =article= would probably be the outer
wrapper around the entire body section of the output, and would be set
as the "content" wrapper in =org-html-divs=. BTW, the html5 version of
=org-html-divs= would be:

#+BEGIN_SRC emacs-lisp
'((preamble  "header" "preamble")
(content   "article" "content")
(postamble "footer" "postamble"))
#+END_SRC

Using =PROPERTIES= on org heading is not really hardcoding. It's the
"org-way" of associating things with document sections/headings.

To recap, I don't really see a compelling reason to specify a
hierarchy of wrappers specific to html5-fancy output. After reviewing
the spec, i do see the value in wrapping org document sections in
=section= tags per the rules in [1] above (from previous email).
