> Issue Type: Bug
> Components: DOM (Level 3 Core)
> Affects Versions: 2.9.1
> Reporter: Ludger Bünger
> Attachments: NodeRenameUserdataAttachOrder.txt

> According to [1], the order how to process a renameNode if a new node is to be created is (numbering added by me for better referencing):
> "If simply changing the name of the given node is not possible, the following operations are performed:
> (1) a new node is created,
> (2) any registered event listener is registered on the new node,
> (3) any user data attached to the old node is removed from that node,
> (4) the old node is removed from its parent if it has one,
> (5) the children are moved to the new node,
> (6) if the renamed node is an Element its attributes are moved to the new node,
> (7) the new node is inserted at the position the old node used to have in its parent's child nodes list if it has one,
> (8) the user data that was attached to the old node is attached to the new node."
> Current Xerces2-J implementation first attaches the userdata to the new node (step 8), then inserts the new node (7).
> So according to the specs, this should by the other way around.
> Attached please find a patch fixing this.
> (The thing puzzling me is: the code was commited by Arnaud Le Hors himself (commit 318496) who also wrote the specs (afaik).)
