A List of Accessible 508 Compliant Content Management Systems / CMS

I’m always on the lookout for accessible open source CMS’s. Here’s a list of some which are 508 compliant.

TYPO3– 508 compliant by using an extension(s) I think? But one big issue before you use it. I almost decided to use it once for a client website whose target audience included mostly novice computer users but then it had this problem with generating simple url’s because of which I backed out.

PostNuke– Any comments on this?

Are there any more CMS’s you know that output accessible code? If so, drop a comment and let me know. I would like to build up this list.

Plone– As said on the website, Plone is 508 compliant, works with all browsers, and is in conformance with W3C Web Content Accessibility Guidelines, level Double-A. Plone is also XHTML and CSS compliant.
