Is the HTML/DHTML that zope generates WAI complient? If not how mcuh work would it take to make it so? I've looked all over the web for this and there doesn't seem to be any info. BACKGROUND DO NOT NEED TO READ IF YOU DO NOT WANT The company I'm working for have a contract with a government agency so the code has to be WAI complient the contest so far is between SharePoint, Lotus Notes and Zope. Lotus Notes is hopeless at WAI Complience and SharePoint has no info on the subject.
