automated wcag validation rules

Hi all,

had a brief discussion with Rich s about a minumum set of automated
conformance criteria

Problem: many automated tools claim to test wcag criteria, but there is no
standardized set (to my knowledge) of conformance criteria rules that can
be checked using automated software. This has lead to a range of tools
claiming to test WCAG conformance when in fact some requirements are out of
step/incorrect.

Has there been any work/discussion on producing a standardized set of
machine testable wcag2 conformance criteria that any tool claiming to be
testing wcag conformance can be tested against?
