The checkpoints in the minimum set are those which, if satisfied, eliminate barriers that would otherwise prevent an identifiable group of users, (with the aid of any applicable client-side software and assistive technologies), from reading, understanding, navigating or interacting with the content. Notes 1. There is no assumption that all users are relying on assistive technology. 2. Any checkpoint which results in a certain group of users' being unable to carry out any one or more of the relevant functions with respect to the content (viz., reading, understanding, interaction and navigation) would qualify for inclusion in the minimum set. 3. Where failure to implement a checkpoint would make reading, understanding, interaction and/or navigation more difficult for some groups, but would not entirely preclude functioning along any of these dimensions, due for instance to the availability of relevant assistive technology, the checkpoint would not be included in the minimum set, but it would be included in the guidelines as "good advice" to authors. Where appropriate success criteria can be defined, such checkpoints would count toward a higher level (i.e., beyond the minimum) level of conformance. The principle expounded here is meant to be equivalent, in substance, to Wendy's original idea as captured in OTACS 2, but offers a less stringent interpretation of what makes content inaccessible to users. Specifically, in order for a checkpoint to qualify, it must make the difference between access and lack of access in any one or more of the four dimensions. These dimensions correspond, broadly, to guidelines 1-3 of WCAG 2.0 as formulated in the latest draft.
