/**
 * Add an annotation explaining the sum constraint and effect the isAs.
 * <p/>
 * Today, this has two parts. First the annotation is truly just
 * documentation in this case. The second part of the constraint creation,
 * where the isA parts are added as elements of the type suffices to explain
 * everything that is needed. In the standard sum constraint in
 * constraints.easik gives this annotation:
 *
 * <pre>
 * &lt;xs:annotation>
 *  &lt;xs:documentation>
 *     Sum is a disjoint generalization of Summand1 and Summand2 and Summand3
 *   &lt;/xs:documentation>
 * &lt;/xs:annotation>
 * </pre>
 * <p/>
 * Each of the Summand entities have an "isA" relationship to the Sum entity
 * at the start of the diagram, so this is reflected in the typing. First,
 * an element of each Summand type is added to the target of the "isA"
 * relationship. Second, since there is no need for a separate element in
 * the schema for the Summand entity, its element is removed from the sketch
 * entity.
 *
 * @param sum
 *            the summand diagram constraint.
 * @todo Why not do this with standard isA relationships as well?
