Chair: Jim Allan, Kelly Ford Latest editor's draft - http://www.w3.org/WAI/UA/2012/ED-IMPLEMENTING-UAAG20-20120827/ Agenda+ Conformance discussion - continued Strawman-- There is no UA that will meet all of the needs of all users. A user agent provides a foundation from which to build an accessible user experience. The user will build on the foundation through the use of extensions or plug-ins and possibly use assistive technology to meet their individual needs. Support for accessibility needs exists in several layers. First, is the platform or operating system. Accessibility features of platforms may include keyboard/mouse/touch navigation, high contrast mode, keyboard enhancements (sticky keys, bounce keys, etc.), some screen reading functionality, some magnification or the ability to choose base fonts and sizes. Second, the base browser, extensions and plugins added to browser functions, and assistive technology added to the platform. The user agent generally is an application that runs on the platform. It may provide additional accessibility features that work in conjunction with the platform (e.g. pass through high-contrast settings) and some my override the platform features (e.g. change the default font, size, and color) in the user agent. Third, are extensions, which are enhancements that are installed by the user and essentially become part of the User Agent. Another layer is plug-ins. These are external applications that render specific content and may use the browser as a delivery mechanism. Plug-ins essentially become the user agent for specific content types. Finally, a user may not have their particular accessibility needs met by the use of the previous layers and add the use of assistive technology(AT). Assistive technology is an application that runs on the platform to enhance the user experience on the platform and its applications (including the browser). The AT may have specific functionality for browsers. Conformance to each of SCs of UAAG20 includes 1 id the platform 2 id the user agent 3 id extension(s) necessary if any 4 id plug-in(s) necessary if any 5 id Assistive technology necessary for specific classes of users. Except for a few SCs (e.g. those related to speech output and synthesizer configuration, need to id others) all SC should be met by a combination of 1-4. Using the above, created a conformance claim for 1.1.1. it got pretty cumbersome. Perhaps breaking out all of the media types is more for testing? Not sure where this will lead. Conformance for 1.1.1 Render Alternative Content [was 1.1.3]: For any content element, the user can choose to render any types of alternative content that are present. (Level A) html Images - alt 1. windows 7 2. Generic 3-5. none needed captions for video 1. OS Lion 2. Generic-Mac 3. none needed 4. media player with captions turned on 5. none needed flash svg canvas longdesc (or whatever) title for abbr etc. (or all titles?) comments welcome before meeting.
