Creates a Position Vector transformation.
A PositionVectorTransformation is a seven parameter geographic (datum) transformation. The seven parameters are three translations in meters, three rotations in arc seconds, and a scale factor in parts per million. The parameters refer to XYZ space. The conversion of features to and from XYZ space is done automatically as part as the method. If the input and output spheroids (ellipsoids) are different, that is also handled automatically. The CoordinateFrameTransformation is similar but uses a different convention when handling the rotation values. To convert between a position vector and coordinate frame methods, change the signs of the rotation values.

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.

The coordinate frame transformation is the same method but with rotations defined in the opposite direction. Make sure you know which method to use. If you change the signs of the rotation values, you can use the other method and get the same results.
