/**
 * This interface and inherited behavior describe the configurable properties defined for a
 * secondary table in the ORM xml.  One or more secondary tables can be declared for an entity.
 * The association of a secondary table to the primary table is defined by PK column joins.
 * <p>
 * Provisional API: This interface is part of an interim API that is still under development and
 * expected to change significantly before reaching stability. It is available at this early stage
 * to solicit feedback from pioneering adopters on the understanding that any code that uses this
 * API will almost certainly be broken (repeatedly) as the API evolves.<p>
