Currently working on an accessibility project for the Government of Canada. We are upgrading a legacy web application and site to comply with WCAG 2.0 usability standards. The site was developed using ASP.Net 3.5, however the front end code is really messy. Not complaining though but it’s rather tedious trying to tidy up the code and make it compliant at the same time.
The GoC (Govt. of Canada) insists that we use their validation software to test the site. after running an initial test we came up with over 800 violations. Some of them seem reasonable but some are really ridiculous. Such as adding “(This link opens in a new window)” after every link that opens in a new window, even though it breaks the readers train of thought.
Here is a good starting point for those who want to know more about why web accessibility is important.
