Here are some ideas that occurred to me upon reading Gregg's conformance analysis: as we proceed down the levels, the semantics that must be represented in the content become increasingly sophisticated. In general newer technologies are more capable of fulfilling these requirements than older technologies, though the difference isn't really chronological, but rather associated with the way in which the content is represented and the attention paid to device-independence and "multi-purposing" as some call it, in the design of the technology. This can be regarded either as a constraint on the levels themselves, that is a requirement that level 1 must be achievable with specified types of technology, or as a consequence of other decisions that we have already made on grounds of importance, namely that higher quality access is achieved as the semantic complexity of the content (and the concomitant processing capability of the software tools) increases. Thus there arguably exists a natural relationship between the success criteria themselves, as we proceed down the conformance levels, and the sophistication of the support provided by the technology. I think this might be a useful observation as we discuss guideline 5.
