The W3C is the developer of specifications for web based content. The are
not a standards board.
There are actually several different standards organization's in this space
both domestically and internationally.
You should definitely be using W CAG 2.0 as your guidance for content
delivered via the web but it is incomplete for content delivered via other
mediums.
