> The Well Known Text (WKT) formatting of {{CoordinateOperation}} objects have the following shortcomings:
> In the formatting of Molodensky Parameters, _Semi-major axis length difference_ and _Flattening difference_ parameters are wrongly set to NaN. Note that this issue happen only for {{CoordinateOperation}} WKT, not for {{MathTransform}} WKT.
> Operation steps inserted for changing axis order are shown as affine transform, which is difficult to read for most users. The formatter should detect automatically when a matrix is square, of size 3×3 or 4×4 and having 1 value on anti-diagonal (except last row) and show instead one of the following operations:
>  * EPSG::15498 — axis order change (2D)
>  * EPSG::15499 — axis order change (geographic3D horizontal)
