I think the description is OK. It's the content of the HTML5 draft that 
is the problem here. If the content of a purported specification is 
defined in terms of a wiki, i.e. a system where everyone and his brother 
can write anything at any moment, it simply isn't a specification.

It puzzles me why no one has written an entry about X-UA-Compatible 
there. Maybe because so few people (among those who understand the 
issue) take this "specification by wiki" seriously. It seems to be 
mostly a write-only system.

That would be brave, but not necessarily useful.

If it's relevant, it should be documented in the validator's 
documentation, instead of just someone's explanation. It's not just a 
technical issue. The question is: what does the validator validate against?

I don't think there's any evidence on such updates taking place 
_periodically_. (What might the period be?)
