Most of the time isn't all of the time. Why are you insisting on 100%?
Not everyone has a visual impairment. Not everyone has a mobility
problem. Not everyone has a cognition problem. We're considering
factors that are most likely to hinder accessibility. Invalid
documents can and do hinder accessibility. Valid documents aren't a
guarantee for accessibility, but they do offer a solid foundation to
build accessibility on.

Is validity restricted to unclosed meta tags, or paragraphs? If so, I
would support a proposal that documents must be valid according to
their specification, with the exception of closing meta tags or
paragraphs. If not, then the following would be inaccessible.

There are far too many validity mistakes that could result in
accessibility issues to list. If this mistake is covered by another
guideline, there will be others that won't. So it comes down to what's
a serious mistake and what's a little mistake. Shall we start to make
a list?
