The working language of the W3C is US English and the official version of a W3C document is the US English language version at the W3C site. However, the W3C tries to reach as many people and organizations around the world as possible by also managing the translations of the specifications. This is based on a community effort of volounter translators from around the World. http://www.w3.org/Consortium/Translation/ 2016-11-17T14:26:00+00:00
