(Not sure if this is how we propose/discuss these sorts of things. Is it ok in email, or do I need to set up a voting thing - and if so, how?) ACTION-263 Review 3.1 with a proposal for clean-up due in 2 weeks http://www.w3.org/2010/01/21-ua-minutes.html#item03 Apologies for having this so close to the conference call itself, but here's my proposed text. It ended up quite verbose, so may require a further sharp edit, but I hope this covers what we discussed (big changes marked with asterisks, and comments with @ signs): Guideline 3.1 Provide access to alternative content. 3.1.1 *** Discoverability *** of Alternative Content: Provide a global option for the user to *** receive visual or auditory cues in the presence of *** alternatives to rendered content (e.g. *** visual icons rendered in proximity of content which has *** short text alternatives, long descriptions, captions, *** and a mechanism for the user to access this alternative content ***). 3.1.2 Configurable Default Rendering: Provide the user with the global option to set which type of alternative to render by default *** and, in cases where the alternative content has different dimensions than the original content, how the layout/reflow of the document should be handled. *** (Level A) 3.1.3 Browse and Render: The user can browse the alternatives and render them according to the following (Level A): (a) synchronized alternatives for time-based media (e.g., captions, audio descriptions, sign language) can be rendered at the same time as their associated audio tracks and visual tracks, and (b) non-synchronized alternatives (e.g., short text alternatives, long descriptions) can be rendered as replacements for the original rendered content. If the new item has different dimensions, then a user option controls whether the dimensions of the original content are used ***(including an indication of, and accessible scrolling or expansion mechanism for, alternative content in cases where the alternatives exceed these original dimensions) *** or the dimensions of the new content, which will cause the document to reflow accordingly. 3.1.4 Available Programmatically: If an alternative *** is contained in the current document (e.g., a short text alternative, not requiring an additional server request) ***, then it is available programmatically, even when not rendered. (Level A) @@@ this may need further rewording, but I think it's more in line with what we mean? not just limited to plain text? @@@ 3.1.5 Rendering Alternative (Enhanced): Provide the user with the global option to configure a cascade of types of alternatives to render by default, in case a preferred type is unavailable. (Level AA) @@@ does this need repeating the "if different dimensions" bit? it should already be covered by Level A requirements above @@@ P -- Patrick H.
