It would be helpful to add a CAPTCHA example that is in accord with WCAG2 to
"HTML5: Techniques for providing useful text alternatives":
http://dev.w3.org/html5/alt-techniques/

Current HTML5 Spec example:

<label>What does this image say?
<img src="captcha.cgi?id=8934" title="CAPTCHA">
<input type=text name=captcha></label>
(If you cannot see the image, you can use an <a
href="?audio">audio</a> test instead.)</p>

http://dev.w3.org/html5/spec/text-level-semantics.html#unknown-images

HTML Action 54 Example:
http://www.w3.org/html/wg/wiki/Action54AltAttribute#CAPTCHA_Images

WCAG 2.0 Technique G143 recommends, if a CAPTCHA test asks the user to type in
text that is displayed in an obscured image, the text alternative is "Type the
word in the image".
