[mapguide-users] MGOS sometimes does a bad rendering of WMS sources

In my example, I guess it's a bug in the "Autodesk® Infrastructure Studio
2013" 
There is a difference between Studio and maestro by choosing the right CS.

*Studio* with the described problem:

<SupplementalSpatialContextInfo>
    <Name>EPSG:31468</Name>
   
<CoordinateSystem>PROJCS["DHDN/*2*.Gauss3d-4",GEOGCS["DHDN/*2.LL*",DATUM["DHDN/2",SPHEROID["BESSEL",6377397.155,299.15281535],TOWGS84[598.1000,73.7000,418.2000,*0.202000,0.045000,-2.455000,*6.70000000]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["false_easting",4500000.000],PARAMETER["false_northing",0.000],PARAMETER["scale_factor",1.000000000000],PARAMETER["central_meridian",12.00000000000000],PARAMETER["latitude_of_origin",0.00000000000000],UNIT["Meter",1.00000000000000]]</CoordinateSystem>
  </SupplementalSpatialContextInfo>  

*Maestro* with a normal result of the wms layer:

<SupplementalSpatialContextInfo>
    <Name>EPSG:31468</Name>
   
<CoordinateSystem>PROJCS["DHDN/*3.*Gauss3d-4",GEOGCS["DHDN/*3.LL*",DATUM["DHDN/3",SPHEROID["BESSEL",6377397.155,299.15281535],TOWGS84[598.1000,73.7000,418.2000,-*0.202000,-0.045000,2.455000*,6.70000000]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["false_easting",4500000.000],PARAMETER["false_northing",0.000],PARAMETER["scale_factor",1.000000000000],PARAMETER["central_meridian",12.00000000000000],PARAMETER["latitude_of_origin",0.00000000000000],UNIT["Meter",1.00000000000000]]</CoordinateSystem>
  </SupplementalSpatialContextInfo>

Same EPSG code, but different result.
