Dear Bjoern,
whilst reviewing the status of the CSS3-Speech Module I came across  
what seems to be an unanswered message from you (at least I can't find  
any relevant reply in the public mailing-list archive). I realize that  
you raised your point way back in early 2007, but I might as well  
address it now ;)

(1) the square bracket notation is used not only in CSS-Speech, but  
also in other modules, and in fact in CSS 2.1 too (for example [1]).

(2) optionality is represented using a question mark, square bracket  
is used for grouping.

Regards, Daniel
