DOMUserDataHandler
When associating an object to a key on a node using setUserData the application can provide a handler...

DOMUserDataHandler::handle
virtual void handle(DOMOperationType operation, const XMLCh *const key, void *data, const DOMNode *src, DOMNode *dst)=0
This method is called whenever the node for which this handler is registered is imported or cloned.
