This method implemented by the stream in processSkippedCases is called once per chunk, passing in the list of skipped records, in a parameter of type BatchProcessingSkippedRecordList. This allows any required processing for the skipped records, for example creating notifications, to take place. Because skipped records can be re-processed, either in the chunker or in a separate run of the batch program, it's important that any actions, like the notification, make it clear that subsequent processing may have resolved the issue and this should be verified before taking any corrective action.
