Javascript and WCAG 2.0

Hello all.

Could I please get some feedback on the use of Javascript and compliance with WCAG 2.0?

I had a meeting with developers about the use of JavaScript . I explained that JavaScript is an accessible technology and can be used if used in an accessible way. In addition, I explained that functionality provided by the use of JavaScript does not have to exist when JavaScript is disabled or not available, as long as the content is still available. There was some argument on this point, particularly about the content being available. I said that if content becomes or remains hidden when JavaScript is disabled or not available that this is considered a failure.

One of the developers said they could optionally post a conformance statement on their application indicating what technologies are required to use the application.

I have read conformance requirements 4 and 5 under Understanding Conformance Requirements<http://www.w3.org/TR/UNDERSTANDING-WCAG20/conformance.html>; and the definition for Understanding Accessibility Support<http://www.w3.org/TR/UNDERSTANDING-WCAG20/conformance.html#uc-accessibility-support-head>; in WCAG 2.0 and do not see this.

Any thoughts on this?

Thanks in advance.
