Description
MapGuide doesn't use EPSG codes and uses WKT to specify their coordinate systems, so we can add WKT parsing to Proj4js

from Fredrik Blomqvist:
While trying to load an ArcGis map that depended on wkt for projection into OpenLayers I found your latest/upcoming Proj4js wkt addition, http://trac.osgeo.org/proj4js/changeset/1873.
When trying it out I believe I found and fixed couple of issues. See attached patch. Summary:
Here's the complete WKT string I used (from http://OneMap.sg)
"PROJCS[\"SVY21\",GEOGCS[\"SVY21[WGS84]\",DATUM[\"D_WGS_1984\",SPHEROID[\"WGS_1984\",6378137.0,298.257223563]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"False_Easting\",28001.642],PARAMETER[\"False_Northing\",38744.572],PARAMETER[\"Central_Meridian\",103.8333333333333],PARAMETER[\"Scale_Factor\",1.0],PARAMETER[\"Latitude_Of_Origin\",1.366666666666667],UNIT[\"Meter\",1.0]]"
HTH, thanks for enabling great mapping services!
