The initial full notification will list all existing resources, so given 
the resource-lists document (index) doesn't exist it will not be 
indicated within the notification. So the element will be indicated and 
possibly zero or multiple documents within the pidf-manipulataion 
collection. So there are no reason indications like error codes within 
the notifications, the resources simply doesn't exist within the 
notification body. So a client knows what it tries to retrieve and the 
full notification will list what resources are available, i.e. some 
pretty simple logic on a client side.

br, jari
