Sure, there may be a correlation, but given that we've established that
sites with validity issues can also be accessible, it is not a causal
relationship between validity and accessibility.  The correlation may be
caused if the careful, professional developers who choose to attend to
validity are more likely to also attend to accessibility.

What would be interesting to see is a study of sites where the developer
had accessibility as a goal and those sites divided into two groups -
those where validity was or was not an additional goal.  That would be a
fairer comparison that would remove the mass of developers who care
neither about validity nor accessibility.
