Proposal: sufficiency criteria for WCAG 2.0

At the face to face meeting, there was support for the idea of
defining what Gregg aptly termed "sufficiency criteria" that would
specify the conditions under which a checkpoint could be deemed to
have been satisfactorily implemented. It was argued that (1)
sufficiency criteria should not be confused with the demands of
automated testing procedures--that is, having clear criteria of
implementation is not equivalent to the removal of all factors
requiring human judgment; and (2) the criteria should not be regarded
as "minimum conformance requirements" but rather as specifying in
greater detail what was needed to satisfy a checkpoint.

These considerations have been borne in mind in the following
proposal, which specifies putitive sufficiency criteria at the
checkpoint level. As it stands, the proposal is incomplete, but it
should provide an adequate basis for discussion.
