Those properties were designed for aural browsers using speech synthesis 
to read the content of a page, not to control multimedia in a page 
itself.  Also, attempting to hijack those properties for use with 
multimedia content could create difficulties as you would have to define 
how the HTMLMediaElement's volume and muted properties interact with 
those CSS properties, if at all.
