> This projection is basically the standard Transverse Mercator with a zone number prefixed in front of the Easting coordinates, with Z*1E6. See §1.3.5.2 in IOGP Publication 373-7-2 – Geomatics Guidance Note number 7, part 2 – April 2015.
> This case should not be handled like other projection in SIS. It should instead be handled by a special {{MathTransform}} implementation, which is *not* a {{NormalizedProjection}}, but would be pre-concatenated before the sequence of transforms (including the normalization matrix) that compute a Transverse Mercator projection.
