I thought you meant, per DTD.

Yes and no.  The problem with the FOSI was that even though it 
worked, it was hard to specify style on elements in context 
when the contexts were complex.  We combine context and 
local stylesheets.  So, a parentage can be used, but a local 
stylesheet can introduce a new one, so the complexity is 
localized as well.  Conservation of complexity:  we have 
more stylesheets to manage per instance.
