Aural CSS (ACSS) and SABLE

Volume

ACSS defines volume property, e.g.

   volume: loud

Number (0 - 100), Percentage or enumeration

• silent, x-soft, soft, medium, loud, x-loud

SABLE defines volume tag, e.g.

   Please speak more <volume level="loud">loudly</volume>.

Number (0 - 1.0), percentage or enumeration

• quiet, medium, loud, loudest

Sets only the volume, thus quiet is not a whisper.
