The WCAG Samurai Errata are now available
It took nearly two years, but two days ago on 26 February 2008, version 1.0 of the WCAG Samurai Errata for WCAG 1.0 were finally published. As stated in the Introduction, this version is also likely to be the final version.
A quick summary for anyone who is not familiar with the WCAG Samuari or their WCAG 1.0 errata: The WCAG Samurai consisted of a group of accessibility and standards-aware web developers brought together by Joe Clark in 2006. The group's goal was to create a document that provides corrections and updates for the Web Content Accessibility Guidelines (WCAG) 1.0.
The reason to provide corrections is that since WCAG 1.0 was originally published by the W3C in 1999, both web browsers and assistive technologies have evolved. At the same time, accessibility-aware web developers have learned and invented a lot of techniques for building accessible websites. Developers have also learned that some of the techniques that were useful in the past are no longer needed or even cause problems for users.
The WCAG Samurai errata thus removes, rephrases, and adds information that makes WCAG 1.0 more applicable to today's Web. You might also want to read Joe Clark's WCAG Samurai errata released, where he talks a bit more about the errata and the development process used.
So do the WCAG Samurai Errata actually contain any improvements? Yes, definitely. I don't agree one hundred percent with every word in the errata, but all in all I think they make a lot of sense and match what I strive for in my daily work.
Note that you can't use the WCAG Samurai Errata as a standalone document. It should be used in combination with W3C's WCAG 1.0.
