I was pulled off this for a while to get another project done. Looking at this 
again and I was able to get the feature geometry name.  However, now I’ve run 
into a new issue. I’m getting this exception:
OSGeo.FDO.Common.Exception: 'InvalidFormat:
Parameter 'height' can not be empty.


This doesn’t make any sense to me because there is no “height” argument when I 
check the function arguments.

Plan B then is to get at this class definition through the FDO IConnnection,

Make a IDescribeSchema command (using the correct CommandType enum as 
previously stated), execute it loop through its results until you find the 
matching feature class which lyr.GetFeatureClassName() should tell you the name 
of the feature class to look for ...

... Unless that method too throws "not implemented", in which case ... what 
kind of an implementation of the MapGuide API is this?

Ugh…Now I’m getting a “not implemented” exception on that method.  Starting to 
wonder if this is even possible from Map 3D.
