Section 508, which applies to government sites (and I think their contractors) used to have its own standards but is now aligned with WCAG 2.0 AA. Most countries have done the same. You're never going to have standards for software as clear-cut as architectural standards for ramps and such, the factors for software are too complex. There are only a few digital accessibility standards that are very specific, like color contrast between foreground and background at particular font sizes. There is a need for more specifics from the government in specific areas. For instance WCAG 2.0 AA says videos have to have captions but do you have to wait before making a video available until the captions are ready? If you have thousands of hours of uncaptioned video, would it be sufficient to produce captions by request with a reasonable turnaround time? TV broadcasters and DVD publishers have already had rules to follow but as video has become commonplace, regulations haven't kept up.
