- Initially -- at beginning of Web -- none
- before many of the accessibility problems arose
- Proliferation of different guidelines
- disability-specific
- technology-specific
- legacy-based
- "Unified Guidelines" (compiled Trace version)
- W3C/WAI WCAG 1.0, ATAG 1.0, UAAG 1.0
- WCAG 1.0 subsets and spin-offs, and new versions developed in
isolation
- ATAG 1.0 & UAAG 1.0 only implemented incrementally
- WCAG 2.0 in development
- International convergence onto WCAG 2.0, plus ATAG & UAAG?
