Some comments on WCAG 2.0 presentation from August 31 2007

Hello Shawn,
here is one minor point on the PPT presentation of the WCAG 2.0 :
1. In slide 5, notes section :
Original text : WCAG provides a provide common definition for accessible 
content, a benchmark. this sentence is not clear. May be one word should 
be removed : provide. What does "a benchmark" standing alone mean in 
this context? That WCAG provides a benchmark?
Otherwise, the text equivalents on the images (located in the notes) are 
very helpful.
Best
