Joe Clark, one of the loudest voices in the world in regards to accessibility, has a boombastic writeup on his weblog that discusses how Movable Type is an application that generates content, and should therefore adhere to the Authoring Tools Accessibility Guidelines or ATAG:
A detail of note here: Many browsers comply with most of UAAG, and we have a few thousand sites more or less accurately claiming to comply with WCAG, but nothing whatsoever complies with ATAG, including demo projects created by the W3C itself, like Amaya.
We could sit around and wait for inconsequential and minor products like Amaya to comply, or we could go big right away. Movable Type is pretty big, isn’t it? And aren’t they committed to standards compliance and accessibility, at least on paper?
Joe is referring to the A List Apart interview where Anil discussed TypePad’s concerns for accessibility and web standards. Joe’s point being that content generating tools like Movable Type and TypePad should adhere to the ATAG guidelines because they’d be an amazing example of highly-accessible products. I’d have to agree.
