Re: Sv: Question from Last Week's WCAG Teleconference

I agree with Claus that control during any time of the presentation is 
important.

Another example--may be one of the things Claus was thinking about--A 
person who's blind initially hearing textual descriptions of decorative 
elements may want to continue hearing the descriptions if they are 
witty,  or turn them off if they are mundane.

Actually, that goes for anyone... I as a sighted user may want to retain 
decorations if they are entertaining or turn them off if they are mundane.
