Re: Validity

RE: ValidityThe WCAG 1 checkpoint 3.2 stated:
"Create documents that validate to published formal grammars."

This meant your HTML content could validate to the W3C's strict, transitional or frameset DTDs. You could also create your own DTD, publish it on the web and then validate your content according to it.

I assume that the WCAG 2 is going in the same direction where you must be valid but you can pick your own standard, schema or DTD. I don't believe the WCAG 2 could insist that you validate to W3C standards only.

Looking for common ground...

We could create an HTML schema or DTD that permitted common mistakes such as open <br> and <hr> tags because these have little or no affect on accessibility. The schema or DTD would still require all the things that affect accessibility such as closing <table> tags. People that were reluctant to validate against a W3C DTD could validate against this much easier DTD and still keep accessibility.
