Hello Alistair,

If you're talking about any type of AJAX enhancement scripts added to a page, I don't think there's any need to be evaluation work done _before_ the scripts are loaded.

As long as the scripts in question work / are compatible with assistive technologies and are keyboard user friendly, they shouldn't be a concern when we're assessing with WCAG 2.0.

Best practices would encourage the use of progressive enhancement techniques where we would make sure that the basic functionalities are provided before they get enhanced, but as this is outside the cope of we accessibility and therefore, this taskforce, this is not something I feel we should be concerned about.

Best regards,

Denis Boudreau, président
