The attributes listed above include all those used as attributes in the Coordinate subclasses, and some which pertain to attributes in the Point hierarchy.
Note that the values for the attributes in CoordinateDefinitions refer directly to the actual values which occur in the transfer of data with Coordinate, CoordT or TimeClass domains (or their subclasses). For example, if the correct value for y is 6145123, an offset may have been specified as 6100000 (in transform under spatialReferencing), and the value of y given as 45123 in the coordinate. If 45123 happens to be the largest value for y in the data set, then Integer16Unsigned (or Integer32 if there are negative values) is appropriate.
