I think all non-IE browsers that implement document.all go to  
elaborate lengths to make various tests for it fail - the idea is to  
provide it for pages that use it unconditionally, but stop pages that  
test for it from going into an IE-specific code path. However, as far  
as I can tell HTML5 doesn't spec document.all at all, so I'm not sure  
it's relevant for the spec to describe these things.
