Being owned by a Document is not the same as being accessible from the Document by tree walking. A Node once created is always owned by its ownerDocument whether it is currently in the tree or not. > It would make sense to me to be able to "cut" some nodes > out of a document, add them to a DocumentFragment (in which > case their ownerDocument becomes null), and then > subsequently "paste" them, possibly into another document, > at which point they would have an ownerDocument again. Level 1 can't cope with moving Nodes between Documents at all. > If I can't transfer ownership of nodes this way, I don't see > how you could build a cut and paste editor. You can't.
