Just a minor remark: I think your remark on EPUB is not justified. The term 'external' is, in this sense, misleading: it is perfectly possible to include the target of a desribed-at (or longdesc) in the EPUB and make the book self contained for offline reading.

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.
