/**
 * The concern of the project is provide runtime values based on the model. <p/>
 * The values in the model remain untouched but during the process of building a
 * project notions like inheritance and interpolation can be added. This allows
 * to have an entity which is useful in a runtime while preserving the model so
 * that it can be marshalled and unmarshalled without being tainted by runtime
 * requirements. <p/>We need to leave the model intact because we don't want
 * the following:
 * <ol>
 * <li>We don't want interpolated values being written back into the model.
 * <li>We don't want inherited values being written back into the model.
