I’ve been really impressed with the WCAG 2.0 guidelines. This is a big improvement in the way the guidelines are presented and worded that I think will make adoption much much more likely. This here page answers the inevitable question: how does WCAG 2.0 line up against section 508? On one hand it adds specifics and details: sucess criteria and techniques for achieving success. On the other WCAG 2.0 doesnt assume the use of HTML to present web-based content - so some detail that is explicit in section 508 has been moved to other sections within the document that provide technology-specific details.
