035 * A test which demonstrates maven's recursive inheritance where
036 * a distinct value is taken from each parent contributing to the
037 * the final model of the project being assembled. There is no

039 * each model in the lineage is providing a value that is not present

041 * down in the lineage are bubbling up where they should.
