The SDK example ReportsExample shows us how to specify Item Types to be used in a report.
How do we add element properties to a report definition? For example, if my schema should be attached only to closed planar elements, how do I add element metrics such as area and perimeter to my report definition?
It looks like I should call ColumnDefinitionNode::SetAccessors, but ReportColumnAccessor seems to apply only to ECProperties and not element properties.
