I'm not suggesting that we should require UAs to follow heuristics. Only to accept that this document will not meet all requirements, and that we have to address repair strategies and possibly consider more in later versions. The HTML spec may not go far enough to highlight what's important for structured navigation. Minimal requirement is navigation of document structure. However, you need to add filtering before its useful.
