An individual element in a traversal result.

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
The NATraversalResultElement is a Feature in one of the three feature classes (edges, junctions, turns) composing the NATraversalResult that holds how the NetworkElement was traversed during network analysis.
The SourceID represents the SourceID in the NATraversalResult's feature class, not the SourceID of the feature class in the NetworkDataset.
You must use SourceByID on the INATraversalResult interface to get the NATraversalResultSource and then get the Location or the Table from the INATraversalResultSource interface to find the source feature class.
