<comment> With new technology such as roles within the WAI, you can assign the role of the object in a programmatically understandable way. So if assistive technology knows the role of a picture is as a bullet, or that a star means that something is required, or that spacer.gif is for spacing - why do you have to also fill in the alt tag? Proposed Change: Add to the list of options for SC 1.1.1: The role and behavior of non-text content can be programmatically determined. </comment> <discussion> I can't remember if roles were considered in the context of SC 1.1.1. Nevertheless, I'm not entirely comfortable with adding role as a fifth option, because of option 4 (knowing the role of captchas does not make them accessible). Role information could be added to the other options, resulting in the following: 1.1.1 For all non-text content, one of the following is true: * If non-text content presents information or responds to user input, text alternatives serve the same purpose and present the same information as the non-text content. If text alternatives cannot serve the same purpose, then text alternatives at least identify the purpose of the non-text content<ins>, or the purpose of the non-text content can be programmatically determined</ins>. * If non-text content is multimedia; live audio-only or live video-only content; a test or exercise that must use a particular sense; or primarily intended to create a specific sensory experience; then text alternatives at least identify the non-text content with a descriptive text label<ins>, or the purpose of the non-text content can be programmatically determined</ins>. (For multimedia, see also Guideline 1.2 Provide synchronized alternatives for multimedia .) * If the purpose of non-text content is to confirm that content is being operated by a person rather than a computer, different forms are provided to accommodate multiple disabilities. * If non-text content is pure decoration, or used only for visual formatting, or if it is not presented to users, it is implemented such that it can be ignored by assistive technology<ins>, or the purpose of the non-text content can be programmatically determined</ins>. </discussion> <older_issues> Couldn't find any about roles in this context. </older_issues> <proposed_response> [PARTIAL ACCEPT] (depends on discussion). </proposed_response> Regards, Christophe -- Christophe Strobbe K.U.Leuven - Departement of Electrical Engineering - Research Group on Document Architectures Kasteelpark Arenberg 10 - 3001 Leuven-Heverlee - BELGIUM tel: +32 16 32 85 51 http://www.docarch.be/ Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
