Ok, I'll stop making a nuisance of myself, now. ;) I forget that you are all probably quite fully aware of all the debate that goes into this sort of thing on various developer specific lists (like css-discuss).
I guess that is one more argument for the DL folks. ;) It's always seemed a little odd to nest "definitions," but I suppose that is a quibble - you can argue that a heading isn't much different. I'll consider this an authoritative (and googlable) answer for when 5 rolls out. Thanks for your time, Tim
