| * reflectively compute the relative value, with respect to the population |
| * count for the disease model label value, for the remaining properties. If |

| * {@link DiseaseModelLabelValueRelativeValueProvider} would need to be |
| * defined that implemented {@link RelativeValueProvider#getProperties()} |
| * such that it first called its super-class |
| * <code>super.getProperties</code> (i.e., |
| * {@link DiseaseModelLabelValueRelativeValueProvider#getProperties()}) to |
| * get the list of filtered properties. Then, it would need to remove any |
| * non-relative properties that it knows about from that list. |
| * <p> |
| * There would probably be no need for the new class to override |
| * {@link DiseaseModelLabelValueRelativeValueProvider#getRelativeValue(EStructuralFeature)} |
| * as the relative values are computed such that the new property values are |
| * obtained reflexively, so they should be found. This assumes that the new |
| * values are relative to the population count (i.e., |
| * {@link DiseaseModelLabelValue#getPopulationCount()}). If they're |
