This message is used to establish consistency between the remote sequence and the corresponding local collection. It contains all insert and delete operations that were performed on a collection. Clients send this message when a local collection is updated using the collection API (IListView.removeItemAt(), etc) or the Single Managed Object API (DataService.createItem()). The remote destination sends this message when the remote sequence is updated and items are moved or removed and inserted. This body property contains a list of UpdateCollectionRange objects that indicate just how the collection was modified. Applying the update collection ranges inorder will establish a consistent ordering of the items within the specified collection.
