Editorial change to 3.5.2 Example

[johnfoliot]

The current example shows the following:
<aui-distraction="moving ad">

aui-distraction is supposed to be an attribute, and not an element.

I believe the correct example would be:
<img src="animated.gif" alt="animated banner advertising for Foobars" aui-distraction="moving ad">
