revisionflag support in HTML-XSLTs

["Christian Roth" <roth@infinity-loop.de>]

Hello,

is there support for DocBook's "revisionflag" attribute in the HTML
output of the current DocBook XSLTs?

I'd like to visually style elements that have been added/changed by
applying some  appropriate CSS. So what I was looking for is e.g.

DocBook: 
<formalpara revisionflag="added">
  ...
</formalpara>

to become in 

HTML:
<div class="dbrev_added">
  <p>...
  ...
</div>

to go along with 

CSS:
.dbrev_added { color: green; }


Regards
Christian
