        doesn't exist.  Can also take a tuple as a parameter, (target, child),
        where child is the index of the attribute in the WKT.  For example:

        >>> srs = SpatialReference(wkt) # could also use 'WGS84', or 4326

        EPSG
        >>> print(srs['AUTHORITY', 1]) # The authority value
        4326
        >>> print(srs['TOWGS84', 4]) # the fourth value in this wkt
        0
        >>> # For the units authority, have to use the pipe symbole.
        >>> print(srs['UNIT|AUTHORITY'])
        EPSG
