Workspace extension to support representations in a geodatabase.

Extended Error Information
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.

Remarks
RepresentationWorkspaceExtension is a workspace extension useful for creating and managing feature class representations. RepresentationClass is a feature class enabled with representation capability using RepresentationRules and Overrides stored within the geodatabase. Use IRepresentationWorkspace.CreateRepresentationClass method to add representation information to a feature class.
IRepresentationWorspaceExtension is the inteface that has methods and properties listed for representation classes present in a workspace.
New RepresentationRules object which is a collection of representation rules based on which features are rendered, has to be created or a reference to rules of an existing representation class has to be made prior to the convertion of a regular feature class into a representation class.
