Definitions: At the W3C “A vocabulary and associated APIs for HTML and XHTML” - At the WHAT WG “This specification evolves HTML and its related APIs to ease the authoring of Web-based applications.” - PC Magazine Encyclopedia “HTML5 is designed to provide a comprehensive application development platform for Web pages that eliminates the need to install third-party browser plug-ins. HTML5 provides support for 2D graphics (canvas element), document editing, drag and drop, browser history management, video playback and local file storage.” -

"Implementors should be aware that this specification is not stable. Implementors who are not taking part in the discussions are likely to find the specification changing out from under them in incompatible ways."

 W3C HTML5 A11y Task Force tracks Issues and Bugs  Most Major Issues have proposals attached  Many Bugs are related to Issues  Some issues are not yet addressed Canvas, Video/Audio, ARIA Mappings Alternative Text and Table Summaries Accesskeys Status of Progress and Meter elements Image Analysis Heuristics
