/**
 * <!-- begin-user-doc -->
 * This class is purely used to hack around a problem with the translators and representing
 * the IMultiRelationshipMapping.mapKey feature in the xml.  Added this object to correspend to the
 * map-key type in the xml since the translator path approach caused the map-key element
 * to be added even when the mapKey String was null.  This occurred when you added a new 1-m or m-m
 * mapping to the orm.xml via the structure view.
