[Orgmode] [Feature request] CSS tag classes for headlines

[Peter Westlake]

Would it be possible to give exported headlines a class based on their
tag or TODO?

For instance, instead of just labelling the tag, like this:

<h2 id="sec-10">Windows builds fail with "Error 66"<span
class="tag"><span class="CLOSED">CLOSED</span></span></h2>

I would like to change the appearance of the whole headline:

<h2 id="sec-10" class="headline-tag-CLOSED">Windows builds fail with
"Error 66"<span class="tag"><span
class="CLOSED">CLOSED</span></span></h2>

The use case is that I need to put a list of bugs up on the wall, and it
would be nice if closed ones could be greyed out. In fact, the whole div
containing the headline and text could be given a class, and child
elements could be identified using CSS selecters.

<div id="outline-container-10" class="outline-2 outline-2-CLOSED">

Peter.
