[O] Adding a class to html export of a list

[Tony Day]

Hi,

I would like to add a class to a list on html export.  So, this:

#+BEGIN_EXAMPLE 
- [[#][Home]]
- [[#about][About]]
- [[#contact][Contact]]
#+END_EXAMPLE

becomes this:

#+BEGIN_EXAMPLE 
<ul class="nav">
<li><a href="#">Home</a>
</li>
<li><a href="#about">About</a>
</li>
<li><a href="#contact">Contact</a>
</li>
</ul>
#+END_EXAMPLE

I've been back and forth through the docs and I can't place a way to
do it, other than to drop back to raw html (and I love my plain
lists).

Any help appreciated.
