All document events are batch events. The batch size depends on the number of documents the user has selected when the event occurs. A single-document operation is a batch operation with size 1. For example, if the user selects four documents and then uses the Start Change command, the event procedures will execute on a batch of four documents. If the user has selected only a single document, only that document is processed, but all batch events still occur in order.
