Maurizio: And what I think I've proved with my examples is that valid code is not the only way to have some accessibile page. Roberto C: Maybe you don't need to prove things we all agree on: an accessible page can be a not valid page, we all agree on this. Maurizio: We have to put in p1 only things that always raise up real accessibility walls, things that make content impossible to access, things disabled users can't live without. If a text equivalent is missing, there's no way to access to that content. No way. Roberto C: Not true, Maurizio. I could say that not all missing text equivalents represent a problem; decorative images do not need any equivalent text, but why should we focus on exceptions in making WCAG rules? Simply we don't have to. I think that saying that equivalent text is strongly requested is ok for WCAG, and it's ok to put it at level 1, because it represents a strong rule which is one of the bases in making a page accessible. Maurizio: So you should demonstrate that all invalid pages (not only some of them) makes content really inaccessibile, not only sometimes harder to access and understand: it is a very different concept. If you can demonstrate this, I will agree to put validity in p1. Roberto C: I think this is not the right direction; i've just shown you that it's not true that every missing alt text makes content really inaccessible, so I don't need to demonstrate that all invalid pages are not accessible. Once again, we cannot take care of vendors needs and browsers or assistive technologies' bugs and model WCAG 2.0 only on the present snapshot of the Web; browsers and assistive technologies should adopt web standards, not the contrary! WCAG 2.0 guidelines will last many years, so they must have the same long term view WCAG 1.0 had. Please, let's not base the WCAG 2.0 on some exception which should be handled as an exception, not as a rule. Maurizio: But then we should decide if semantic web is a mission of the wcag... Roberto C: Some (important) people says that semantic web will be tomorrow's Web. Does anyone of us imagine or wish a not accessible Web? I don't think so. Semantic web cannot be not accessible, of course.
