possible spec update to include in DITA 1.2

["Grosso, Paul" <pgrosso@ptc.com>]

I haven't dug it up, but I believe there was some discussion 
earlier in the TC of changing or defining the meaning of some 
attributes when they appear on the root element in a topic 
(toc was one, I think there are others).

Does anyone remember this?  Is this still something we want
to do in DITA 1.2?
