Hi all,

I would like my source blocks to be exported to HTML as textareas with a 
class attribute -- so I can later use this in my javascript code. I can 
use ":textarea t" [1], but it seems that other attributes except width 
and height are ignored:

#+ATTR_HTML: :textarea t :class testing
#+BEGIN_SRC n3
My code
#+END_SRC

gives

<textarea cols="80" rows="1">My code
</textarea>

and, testing without ":textarea",

#+ATTR_HTML: :class testing
#+BEGIN_SRC n3
My code
#+END_SRC

gives

<pre class="src src-n3">My code
</pre>


Preferably, I want the following html:

<textarea cols="80" rows="1" class="testing">My code
</textarea>

Is there a way to achieve this?

Thanks,
Martin
