LC-511 Proposed Resolution

From: Ben Caldwell <caldwell@trace.wisc.edu>
Date: Tue, 16 May 2006 23:11:45 -0500
Message-ID: <446AA281.4060201@trace.wisc.edu>

The following is a proposed resolution for Last Call (LC) issue #511:

Commenter: Steven Faulkner
Context: Success Criterion 1.4.1
Comment:
Comment Type: TE
Comment (Including rationale for any proposed change):

The success criterion refers to "Text or diagrams". From the definiton 
of "text" in Appendix A:Glossary, it appears that images of text are not 
included. This can result in web authors using images of text (with a 
foreground/background luminosity ratio of less than 5:1) to circumvent 
this Success criterion.

Proposed Change:

Include an explicit reference to the inclusion of images of text in 
terms of this success criterion.

Proposed Resolution: (accept)

Revise SC 1.4.1 and 1.4.3 as follows:

[current]
1.4.1  Text or diagrams, and their background, have a luminosity
contrast ratio of at least 5:1.
1.4.3  Text or diagrams, and their background, have a luminosity
contrast ratio of at least 10:1.
[/current]

[proposed]
1.4.1  Text, images of text, or diagrams, and their respective 
backgrounds, have a luminosity contrast ratio of at least 5:1.
1.4.3  Text, images of text, or diagrams, and their respective 
backgrounds, have a luminosity contrast ratio of at least 10:1.
[/proposed]
