Introduction
When exceptions are created based on built-in rules, the base type is always set to "Stock". For rules which are defined by you, the base type will be "Custom". The ZoneStop base type is used to designate exceptions created specifically when a zone is configured with the "MustIdentifyStops" property set to true.
