Those are unrelated issues, aren't they?  The linear list I was 
referring to is the proposed parentNode (or equivalent) chain; order 
there is well-defined, presumably.  For each element in this list, one 
can have multiple listeners for the event; the dispatch order here is 
currently undefined, but that could be changed.

You'd probably have to check with the folks who wrote DOM2 Events, if 
the question is why the spec says what it says.

If the question is about current implementations, nothing obvious jumps 
out at me in the one implementation I'm familiar with (Gecko's).
