With the publishing of the EPUB Accessibility specification, there’s been a noticeable up-tick in people looking to produce accessible content. Normally, that would be a great thing, but it also means more people are hitting on the limitations of reading systems for accessibility. It’s true, EPUB reading systems aren’t just a headache for designers!
Providing extended descriptions is one of the more problematic areas, as we’ve been searching for years now for solutions that meet publishers’ needs and are also broadly supported enough that they can be reliably used. That headache popped up again this last week, so I thought I’d detail the anatomy of finding a solution.
