Whilst I agree H and Hx is relatively under specified in the XHTML 2 draft - 
do we really want to make document outlines all the same?  I would consider 
document outlines the sort of value added functionality that can 
differentiate between user agents, I certainly can't see any requirement for 
interopability in them, they're not content, they're just a convenient 
overview for the user, what the user wants here should be paramount, not 
some defined algorithm.
