The link (anchor element) could be hidden from users who don’t explicitly request extended descriptions using the media query taht several contributors to this discussion have proposed. This is a good illustration of the fact that no single solution meets all requirements or should be considered appropriate for all use cases. I’ve raised privacy concerns about linking to external descriptions. In addition, there are circumstances in which network access is restricted or unavailable (testing scenarios are often good examples here, due to security considerations). Ideally, everything, including descriptions, needs to be loaded at once in such cases. I’ve also raised concerns about the possible use of links to external descriptions in EPUB, as it limits the offline use of books, thus placing readers with disabilities at a disadvantage with respect to their peers. An EPUB book should be a self-contained package that can be copied onto a device and read without requiring access to external resources in order to be accessible to the user. In essence, I am not in agreement with the requirements articulated by the digital publishing community in connection with extended descriptions, although I think those requirements can be met without significant changes to Web technology. ________________________________ This e-mail and any files transmitted with it may contain privileged or confidential information.
