As we look at WCAG Next we might consider criteria like 1.3.1 and 4.1.2 as
guidelines. 1.3.1 can be decomposed functionally. There are objects that
support navigation like headings. Others support associations of objects
(table headers, and table data) as well as labels and controls 1.3.2 could
be interpreted as an SC under 1.3.1 e.g. sequences can be programmatically
determined. Separation of style from meaning really seems like the core
guideline, not the more vague, flexible data.  It gets at the relationship
between markup language and accessibility.

I think a functional dissection of this concept into discrete components
might be the technology independent way to parse refined semantics for
success criteria.
