/**
 * Add an annotation explaining the equalizer and effect the isA.
 * <p/>
 * Today, this has two parts. First the annotation. For example in the
 * standard equalizer constraint in constraints.easik gives this annotation:
 *
 * <pre>
 * &lt;xs:annotation>
 *  &lt;xs:documentation>
 *     Equalizer(f3); B(f4) ;C(f5) ;Codomain =
 *     Equalizer(f1); D(f2) ;Codomain
 *   &lt;/xs:documentation>
 * &lt;/xs:annotation>
 * </pre>
 * <p/>
 * In addition, the equalizer entity has an "isA" relationship to another
 * entity at the start of the diagram, so this is reflected in the typing.
 * First, an element of equalizer 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 equalizer entity, its element is removed from the
 * sketch entity.
 *
 * @param eq
 *            the equalizer diagram constraint.
 * @todo Why not do this with standard isA relationships as well?
 * @todo The equalizer element should be added in some way so there is a
 *       "minoccurs" of zero.
 * @todo The equalizer does not really need a "key" element, but what if
 *       other constraints refer to it.
