/**
 * Specifies multiple secondary tables for an entity.
 *
 * <pre>
 *    Example 1: Multiple secondary tables assuming primary key columns are named the same in all tables.
 *
 *    @Entity
 *    @Table(name="EMPLOYEE")
 *    @SecondaryTables({
 *        @SecondaryTable(name="EMP_DETAIL"),
 *        @SecondaryTable(name="EMP_HIST")
 *    })
 *    public class Employee { ... }
 *
 *
 *    Example 2: Multiple secondary tables with differently named primary key columns.
 *
 *    @Entity
 *    @Table(name="EMPLOYEE")
 *    @SecondaryTables({
 *        @SecondaryTable(name="EMP_DETAIL",
 *            pkJoinColumns=@PrimaryKeyJoinColumn(name="EMPL_ID")),
