Hi Daniel!

Well, we are in the middle of the "exception vs return value"
discussion, which is a quite old one...

I'd like to indicate a fault, not return an empty model (which does not
do any harm).
Probably I should throw an exception in the C++ code of an
AttributeMapping, which will result in some sort of error message.

Cheers, Achim
