ARIA has been put forward as a mechanism for retrofitting accessibility to existing DOM scripting-based systems. Legacy systems using DOM scripting consist predominantly of text/html and of SVG to a minor extent. HTML 5 is the spec for processing text/html even if authors aren't knowingly using HTML5. It follows from browser software architecture that application/xhtml+xml inherits the above-DOM processing from text/html. Which other languages besides text/html, application/xhtml+xml and SVG is ARIA expected to cater for? Surely potential future languages that have not yet been implemented in browsers in a legacy form should be developed to be natively accessible and not to need retrofitted accessibility in the first place. (MathML isn't used in a way that needs ARIA except perhaps for the live region features.) -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/Received on Thursday, 10 April 2008 18:49:02 GMT
