Regarding 2. How do you feel about index accessors? I.e. for example you can do: myNode.children[5] which returns the same as myNode.children.item(5) This seems equally impossible to implement in ECMAScript, but is something that I think is helpful to authors so not something that I want to stop adding to new interfaces. / Jonas
