I think the answer to that question is both, but X['Y'] seem to have precedents over X.Y.
class MyContainer(OOBTree): title=u'' class MyContent(Persistent): title=u'' Adding MyContent in MyContainer you can traverse MyContainer/MyContent/title or you can traverse MyContainer/title equally well. If I name MyContainer 'title' i get MyContent when I try MyContainer/title.
