Dear WCAG 2 working group,

thanks for your comments! Here are our replies:

Comment 1: Minimum contrast needed for default layout in case
1.4.3 is met via a contrast control

You seem to have somewhat misunderstood our proposal: we are not
suggesting that 1.4.3 should be moved to level A.

But we do think that the success criterion should be slightly
stricter and require the default layout to have a contrast ratio
of at least 3:1, even if a contrast control is provided.

This would be in line with note 4 in the glossary item on 
alternate versions: "Each version should be as conformant as 
possible."

Apart from that we are satisfied with your resolutions.

Comment 2: Why do contrast requirements not apply to lines in 
diagrams and such?

We do realize that there are cases where graphs etc. are so 
complex that it is hardly possible to ensure accessibility 
through appropriate colours.

But there are plenty of much simpler cases where accessibility 
does depend significantly on the choice of suitable colours.

In order to preserve testability the success criteria could be 
restricted to these simple cases that can be identified and 
tested unambiguously.
