Re: Color Contrast (was RE: Coming to a decision on 2.2 - which has long since been lost in this thread)

1.4.3 already applies to icons.

The term text is defined to be:

sequence of characters that can be programmatically determined
<https://www.w3.org/TR/WCAG20/#programmaticallydetermineddef>, where the
sequence is expressing something in human language
<https://www.w3.org/TR/WCAG20/#human-langdef>.
Now, ten years past icons would not fit into this description, but today we
have true iconic text: the search glass, trash can, tool wheel, attachment
paper clip, close window x, minimize underscore, maximize box, house for
homepage, hamburger for menu etc. We can easily develop an alphabet of
programmatically deterministic icon symbols that are in common use today,
and it is large.

A sequence can include only one element, like the number 1, or an icon used
for programmatically deterministic linguistic purpose. Therefore, a lot of
the icons we see today are in fact text. They may not have been text when
1.4.3 was formulated, but they are now. Technology changes. The reason this
was overlooked at the time is because standard uses of icons had not
coalescing so definitively 2008. Mobile devices had a lot to do with this
with their standardization to fill the need to save space.  What we have
today is an icon language that needs to be treated like what it is, well
defined symbols that convey human language.
