Ordered List (Alphabetical) and HTML Export

[Josiah Schwab <jschwab@gmail.com>]

Hi All,

I am using orgmode 8.0.3 with emacs 24.3.  I frequently use
ordered lists with alphabetical bullets.  I have
  (setq org-list-allow-alphabetical t)
in my .emacs.

I just noticed that when I export an alphabetical list using the HTML
exporter, it appears as a numerical list in the rendered HTML.  My
expectation was that the ol tags for this list would look like <ol
type="a">, but instead they are just plain <ol>. (At the end of the
message is a snippet that lets you reproduce this.)

From poking around in ox-html.el (specfically, looking at
org-html-begin-plain-list), I see that there is no code that handles
the list "type".

I spent a few minutes looking at org-list.el, but I'm new enough to
both org-mode and elisp, that I couldn't immediately see how to extend
org-html-begin-plain-list so that it could figure out the kind of list
bullet and properly set the type.

Could anyone help walk me through what one would need to do to get the
desired behavior of HTML export preserving alphabetically bulleted
lists?

Best,
Josiah Schwab

P.S.  Here's an example org snippet.

* Letters
a. foo
b. bar
c. baz
* Numbers
1. foo
2. bar
3. baz
