I had a look through the checklist for WCAG 1 -
http://www.w3.org/TR/WCAG10/full-checklist - to see how technology specific
the checkpoints were.

There are 16 priority 1 checkpoints.

On my first read, I thought that 6.1 and 12.1 are technology specific. 5.1
and 5.2 are about labelling tables - really special cases of a general
requirement, but not actually technology specific in the same sense. At a
stretch I could see an argument that 1.2 and 9.1 (dealing with image
maps) are technology specific, but I don't buy the argument. Leaving at least
10 of 16 checkpoints, by my reckoning, as technology-independent yet
verifiable.

I thought that as I got into the priority 2 checkpoints it would change
drastically. It changed, but not drastically.

I think that the problem to be solved is about working out what is a special
case, that got elevated to checkpoint or guidelines level because we were
thinking about HTML, and what is a general requirement for
accessibility. Shifting a few of our current checkpoints to techniques for
meeting slightly more generally expressed checkpoints would already give us a
good basis document (the WCAG 2.0 draft doesn't lose functionality from WCAG
1, and we haven't considered any substantive change in our requirements yet.)

  What I am arguing is that the meanings have already shifted and that we

  WCAG 1.0) largely, but not entirely technology-specific; the Techniques
  were merely explanations and examples of the checkpoints in many, though
  not all, cases. Recent discourse within the working group has reflected
  the ambiguity by referring to "technology-specific" checkpoints".
  
  We need to clarify the terminology, either by using "checkpoint" to mean a
  technology-specific requirement, or a general strategy of accessible
  design which, though not at the most abstract level, is stated at a level
  of specificity that allows concrete implementation strategies to follow
  from it.
