Which doesn't say anything that these users believe anything more of
HTML validation than it is, it's a very important _part_ of QA. Given
that there are no complete HTML conformance checkers in existence
today for existing HTML technologies.  It seems very strange to remove
one of the few parts of QA available so what have we then got.  Or are
the WHAT-WG members going to step up and implement one?

I thought the whole point of the WHAT work was to make HTML
applications simpler, not more complex, are you suggesting the current
specs are failing in this area?

Could you describe how?  My reading of the error handling defined in
the spec for that situation does not lead to the failure you describe.
 However the unclosed <B> element does exactly that. (in the XHTML

automated QA process, most people rely on non-automated QA methods,
that's fine, if you can find and afford the testers.

tools when no-one's writing it...
