Classes

Name	Description
AggregatedAttribute	Applied to business class properties. Indicates that a property or field references other aggregated persistent objects.

CustomLogics	Arguments passed to the ModuleBase.CustomizeLogics method.
DomainComponentAttribute	Specifies that a target class should be registered in the types info subsystem and should affect Application Model construction.
