+API designers can enable the change tracking (delta) capability on a resource in the Microsoft Graph (typically on an entity collection or a parent resource) by declaring a delta function on that resource and applying `Org.OData.Capabilities.V1.ChangeTracking` annotation.
 
 This function returns a delta payload. A delta payload consists of a collection of annotated full or partial Microsoft Graph entities plus either a `nextLink` to further pages of original or change data that are immediately available OR a `deltaLink` to poll to get the next set of changes as they occur.
