Are there different levels of conformance to ATAG?
ATAG 1.0 has three levels of conformance, which correspond to its three priority levels. Authoring tools that satisfy all priority one checkpoints conform at “Level-A”; authoring tools that satisfy all priority one and two checkpoints conform at level “Double-A”; and authoring tools that implement all three priority levels conform at level “Triple-A”. All conformance levels include relative priority checkpoints.
