I'm giving a talk on web accessibility shortly. I'd like to know the status of mainstream browser support for LONGDESC. I've searched the WAI-IG list archives and used Google to search Web pages. From my searching my understanding is that LONGDESC is not supported by mainstream browsers (cab on the Mac is an exception) - although if you use XSLT you could reformulate LONGDESC to supported HTML element (thanks to Kynn for this suggestion). Is this currently correct? Also what formats can the longdesc file be in? The HTML 4 spec [1] states that: longdesc = uri [CT] This attribute specifies a link to a long description of the image. This description should supplement the short description provided using the alt attribute. But doesn't say whether the file can be HTML, XHTML, plain text, etc. (or that it shouldn't be PDF, GIF, etc.!), can contains JavaScript, etc. Although the example give a file with a .html extension. If use of longdesc is needed to future-proof Web resources for when browser support is available, are their any guidelines on using longdesc?
