Custom WKT Coordinate system ?

Jamo
I'm looking at finally implementing our local grid as a wkt coordinate system.
I've looked at this sometime back, but I have finally got the right paramaters to produce the result I need!

I need to define the wkt as a FITTED_CS with affine.... how do I do this in mapguide.

I might have the elt_x_x assigned incorrectly but either way I'd expect this to pass as a coordinate system...
Is anyone able to help me
FITTED_CS["FIG",
	PARAM_MT["Affine",
		PARAMETER["num_row", 3],
		PARAMETER["num_row", 3],
		PARAMETER["elt_0_2", -6184351.648],
		PARAMETER["elt_0_1", 0.530489207],
		PARAMETER["elt_0_0", 0.848163919],
		PARAMETER["elt_1_2", -3256350.144],
		PARAMETER["elt_1_1", -0.848163919],
		PARAMETER["elt_1_0", 0.530489207]],
	GEOGCS["GCS_EPSG:28356",
		DATUM["D_EPSG:6283",
			SPHEROID["EPSG_7019",6378137,298.257222096042]],
		PRIMEM["Greenwich",0],
		UNIT["Degree",0.017453292519943295]],
	PROJECTION["Transverse_Mercator"],
	PARAMETER["Central_Meridian",153],
	PARAMETER["Latitude_Of_Origin",0],
	PARAMETER["Scale_Factor",0.9996],
	PARAMETER["False_Easting",500000],
	PARAMETER["False_Northing",10000000],
	UNIT["Meter",1]
]

If it helps the following paramaters seem to work for me in FME
COORDINATE_SYSTEM_DEF FIG_2012_PORTBRIS       \
