I know you and other people see it that way (and I'm not saying you're
wrong!). But I'm trying to use language that is acceptable to both sides of
the discussion so not to polarize the discussion any further. I'm trying to
find a compromise that is acceptable to all and try to use neutral language
where I can.

Could you please not simply say that you disagree with me but explain what
you mean?

Could you give me some examples of accessibility problems that would be
caught by requiring validity in the document (your wish) and not by
addressing validity in the techniques for the 'programmatically determined'
success criteria (my proposal)?

In my proposal, we wouldn't need to address validity at all in our
guidelines and view validity as a technique to ensure the other
accessibility requirements can be met. As such I propose to delete them from
the guidelines (all levels) and only talk about techniques.
