/**
 * A mapping defined within the ON clause within a given JoinCondition.
 * 
 * Suppose, for example, that you have the following SQL statement:
 *  *   SELECT ...
 *   FROM DemographicInfo AS a
 *   JOIN TestResult AS b ON a.person_id = b.candidate_id
 * 
 * 
 * Then, this mapping expresses that a.person_id and b.candidate_id
 * map to each other.
