This is useful for batching together a set of changes to multiple ModelItem objects. As an example, in the messaging activities, the changes made from the raised dialogs will impact multiple property values. However, as all of the changes come from the raised dialog, the changes need to be considered as a batch and undone as a single unit of work. For more details on usage, see the Editing Scope sample
