Abstract
XML, by itself, does not have any support for accessibility. XML is extremely flexible, but it needs to flex in the right directions if it is going to support the information necessary to make a document accessible. This is a guided tour of some of the features of the HTML, Web Content Accessibility Guidelines (WCAG), and PDF/UA (Universal Accessibility) standards. It concentrates on file formats rather than User Agent behaviour, since the information needed to make accessible HTML or PDF usually needs to be included in, or able to be inferred from, the source XML.
However, it’s rarely the raw XML that is presented to users. This paper also strays into some aspects of styling the content to make it more accessible.
