Alastair, How do you differentiate between invalid html interfering with
accessibility and interfering with proper functioning? The example you
show is interpreted in different browsers differently, but not just when
assistive technology is in operation. This issue affects potentially
all users with javascript off, not just disabled users.

I'll agree that the invalid code shown makes consistent rendering less
likely in this instance, but I'm not sure that I'd call it an
accessibility issue - just an issue.

Valid code is worth doing for many reasons, but I'm still waiting for an
example that shows me that invalid code creates problems that
discriminates singularly against disabled users. For this reason, I'm in
favor of accessibility standards that address issues that affect users,
but not for a standard requiring valid code.
