I think towards the end of the extension process, we should try to integrate and harmonize them all into one. This may include personalization settings in some specs etc.. but I think eventually we want to come up with one extension and we won't have to worry about jurisdictions choosing between one user group or another... However, this would happen at the end (although throughout we would communicate to avoid conflicts at the end). http://davidmacd.com/blog/WCAG-extension-proposed-integration-into-WCAG.html Cheers, David MacDonald *Can**Adapt* *Solutions Inc.* Tel: 613.235.4902 LinkedIn <http://www.linkedin.com/in/davidmacdonald100> www.Can-Adapt.com * Adapting the web to all users* * Including those with disabilities* If you are not the intended recipient, please review our privacy policy <http://www.davidmacd.com/disclaimer.html> On Fri, Oct 16, 2015 at 5:28 AM, Joshue O Connor <josh@interaccess.ie> wrote: > Hi all, > > On the working group call this week there were a couple of interesting > points raised regarding extensions that require further discussion.
