Re: Removing parsing/storage of CSS 2.0 Aural properties

aloha, david!

recently, daniel weck of the DAISY consortium was appointed an 
editor of CSS3-speech module

http://www.w3.org/TR/css3-speech/

and a revised public working draft of CSS3-speech was issued on 19 
april 2011

http://www.w3.org/TR/2011/WD-css3-speech-20110419

unlike aural CSS, CSS-speech does not allow authors to exercise 
equivalent control over the aural palette as was "available" via 
CSS 2.0/2.1, but note that it is still possible to insert aural 
events using the "cue" properties, defined and described at:

http://www.w3.org/TR/css3-speech/#cue-props

which is something which i certainly hope mozilla will natively 
support -- support for CSS3-speech is a chicken-and-egg problem,
and perhaps, in this case, mozilla can be the incubator...

note, too, that CSS3-speech properties are slated to be supported 
in the next version of EPUB (EPUB 3.0):

Subject: Removing parsing/storage of CSS 2.0 Aural properties

> I plan to remove our code for parsing and storing the values of the

> 1. We've never computed computed values of these properties or
