Specifies how to apply the notification to the collection and its contents. This container and all levels of contents applies the notification to the collection and all of the objects under it. When the subscribed-to change occurs to any one of the collection's objects, DocuShare performs the notification's chosen action, sending email, running a script, or initiating a workflow. This container and immediate contents applies the notification to the collection and only its first nested level of objects. For example, if a collection contains several objects and a subcollection, DocuShare performs the notification action when a change occurs to any of the objects and the subcollection; it does not when a change occurs to an object in the subcollection.
