Thanks Tristan,
This is an excellent contribution.
It is extremely important for an LMS to comply with accessibility standards. In Australia (and I think the USA) it is actually a legal obligation!. If I remember correctly, In Australia IBM got sued duringthe Sydney olympics because the olympic site was not accessible.
It would be great if 2.1 could comply with all the level 1 standards. It sounds as something extremely simple.
We could then have the W3C logos like plone's default installation.
Should we have a TIP also saying that new core packages should follow the guidelines for level 2?
cheers
