I assume the point of these IDL attributes is to allow you to give the
user custom volume and mute buttons.  If you want to mute the video or
change its volume non-dynamically, you could just edit the video file,
so HTML doesn't need to replicate that functionality -- only
JavaScript does, for changes in response to user input.
