Rescinded versus withdrawn cancellations

Rescinded and withdrawn cancellations have identical results: the outcome is that the policy remains in force. However, rescinded and withdrawn cancellations are two different actions. A cancellation may be withdrawn at any time before cancellation notices are sent. If notices have already been sent, then the cancellation must be rescinded so that rescindment notices can be generated. One exception is if multiple cancellations were started for the same policy; if one of them completes successfully, then all the others are withdrawn. This exception occurs because the policy did get canceled, so no rescind notices need to be sent. Having different statuses for rescind and withdrawal can also be useful for statistical analysis and reporting.
