An Esri annotation feature class extension.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

The AnnotationFeatureClassExtension CoClass manages the drawing of annotation features.
The AnnotationFeatureClassExtension is used to configure the drawing properties and symbology for annoation features. The IAnnoClass interface is used to access the AnnotationLayerProperties and GroupSymbols. The IAnnoClassAdmin interface is used to update the properties of the class. ArcMap and ArcCatalog primarily use these interfaces.
