Hello Arthur . . .

I won't be able to verify the following until tomorrow, but you might try taking the spaces out of the datum and ellipsoid names.  That is, use "WGS84" instead of "WGS 84".  You might be able try this more quickly than I can.

Subject: [mapguide-internals] LL84 wkt used in KML Service

Hi, experts

I notice that the wkt used in KML Service is defined as

const STRING LL84_WKT = L"GEOGCS[\"LL84\",DATUM[\"WGS 84\",SPHEROID[\"WGS 84\",6378137,298.25722293287],TOWGS84[0,0,0,0,0,0,0]],PRIMEM[\"Greenwich\",0],UNIT[\"Degrees\",0.01745329252]]";

Creating CS using this wkt in based on the latest code, the result will be Antarctic98.LL (EPSG: 4176), rather than LL84 (EPSG:4326).
I am not sure whether this is as designed or caused by the update in coordinate system component.   Do you have any ideas? Is it needed for us to update the wkt in KML Service?
