For a particular property definition, the Interface collection specifies which interface exposes a member of this type.
This collection is not attached to the default interface for the PropertyDef Automation object; it is attached to the IInterfaceMember interface. For details on how to access a member of an interface that is not the default interface, see Accessing Automation Object Members.
