Response from the Working Group
================================

Makoto asks: Do you mean that the following case would meet SC 1.1.1, 2.4.4
and 2.4.9?

CASE 1:
<p>
<a href="xxx.html><img src="xxx.png" alt="WCAG 2.0"></a>
<a href="xxx.html>WCAG 2.0</a>
</p>

CASE 2:
<p>
<a href="xxx.html><img src="xxx.png" alt=""></a>
<a href="xxx.html>WCAG 2.0</a>
</p>

CASE 3:
<p>
<a href="xxx.html><img src="xxx01.png" alt="WCAG 2.0"></a>
<a href="xxx.html><img src="xxx02.png" alt="WCAG 2.0"></a>
</p>

CASE 4:
<p>
<a href="xxx.html><img src="xxx01.png" alt="WCAG 2.0"></a>
<a href="xxx.html><img src="xxx02.png" alt=""></a>
</p>


Case 1: The first link meets SC 1.1.1 using H37: Using alt attributes on
img elements. It meets SC 2.4.4 and 2.4.9 using H30: Providing link text
that describes the purpose of a link for anchor elements.

Case 2: The first link fails 1.1.1, since there is no text alternative for
the image.

Case 3: Both links meet SC 1.1.1 using H37: Using alt attributes on img
elements. They meet SC 2.4.4 and 2.4.9 using H30: Providing link text that
describes the purpose of a link for anchor elements.

Case 4: The second link fails 1.1.1, since there is no text alternative for
the image.

Regarding redundancy of the links in the cases above, there is no WCAG
requirement to avoid redundancy. It is only advisory.
