In attempting to solve the problems associated with user agent
support, "baselines", etc., in WCAG 2.0 under guideline 4.2, I suggest
that the following requirements be considered.

A good solution should:

1. Construct a recipe for creating baselines rather than a baseline.
   The minimal requirements will vary by time, technology and other

2. Be consistent with, and preferably supportive of, UAAG 1.0. c 3. At
level 1, it should concentrate only on technical issues of
accessibility, excluding questions about cost and broad availability
(i.e., at level 1 if there exists an implementation meeting certain
technical requirements, this should be enough).

4. At level 2 or 3, other considerations may be taken into account,
   including general availability, cost, cross-platform support, etc.

5. Sample baselines should be provided to accompany the guidelines,
   including one that is suggested by the working group for general
   use in designing publicly available Web content, and another that
   captures the implicit WCAG 1.0 baseline. These baselines should be
   non-normative, in keeping with the principle of providing a means
   of defining baselines that will evolve with time, rather than
   fixing a required level of technology support in the guidelines
