[mapguide-users] Add properties to a point

[Kenneth Skovhede, GEOGRAF A/S]

I'm not sure you can modify an existing schema through MapGuide (you can 
through FDO if the provider supports it).

I don't have a sample, as I have not tried to do this.
You might get a hint from the buffer code in the viewer:

            MgClassDefinition classDef = new MgClassDefinition();

            //Set ID property. Hold this segment ID
            prop = new MgDataPropertyDefinition("ID");
            prop.SetDataType(MgPropertyType.Int32);
            classDef.GetProperties().Add(prop);

            //finally, creation of the feature source
            MgCreateSdfParams sdfParams = new 
MgCreateSdfParams("LatLong", srsDefMap, schema);
            featureSrvc.CreateFeatureSource(dataSourceId, sdfParams);

You will need to get a hold of the classDef for the featuresource, and 
then use the Add code.
Finally you have to call UpdateFeatureSource (if it exists).
