Web Content Accessibility Guidelines 2.0 (WCAG 2.0) request for comments

Hi there

I would be grateful if you could simplify the following as found in 

Web Content Accessibility Guidelines 2.0 (WCAG 2.0) 
Principle 1, 
Guideline 1.1
1.1.1 Non-text content, 
3rd point CAPTCHA
 Text reads "....alternate forms in different modalities are provided...."

Could you simplify this by being a bit more verbose...

...different modalities? Do you mean using different methods or 
technologies to provide the content to accomodate different disabilities, 
if so, say so.

There may also be a technical issue here in that providing those different 
methods of representing the content may compromise the security of using 
CAPTCHA in the first place and so render it useless. Thinking like a 
miscreant, if I can exploit an accessibility method used to represent this 
content to bypass the security of that content, then I probably will.

Hope this is helpful

All the best

Andrew Clarke
