Well, I have always used this:

XMLTree.appendchild(Node.clonenode(true));

having XMLTree and Node a different ownerdocument. Would this mean that
using this methods should generate an error? I have used this in two
different parsers (with DOM 1 implementations) and none of them generated an
error.
