Remarks
CustomProperty is a place for developers to attach custom objects to an element. Previous versions of the software required that the specified variant implement IUnknown, but that requirement has since been removed.
A custom object must implement a persistence interface, usually IPersistStream or IPersistVariant. Also, one alternative to writing a custom object is to use a PropertySet or XMLPropertySet.
This property is not used by the core ArcObjects functionality, it is strictly for developer use.
