Re: design flexibility in WCAG 2 (was EOWG for review: Benefits of WCAG 2.0 slides)

Hi Shadi,

To address your main point, I also added into slide 20:
"
Techniques
   for different situations.
   can use other techniques.
"

(In addition to the changes below, including:
To slide 20 [Notes] I added [in bold]: "While WCAG 2 itself provides a stable standard for what users need, <strong>the Techniques provide flexibility in how developers meet users’ needs. There are different Techniques for different situations. And the Techniques are optional; you can use other ways to meet the WCAG 2 success criteria.</strong>"
")

Let us know if this does not cover it.

Thanks,
~Shawn
