The mapping that is sent to your object has the global mappings,
and the local ones as well.
As for your second question, I'm not sure but the example application
was done very early and it wouldn't surprise me if the class is not
used at all. Have you tried a global search? If it's not used anywhere
then it might be a hang over from earlier iterations of the code.
