/**
 * This interface and describes the configurable properties defined for an entity ID mapping in the
 * ORM xml. An ID mapping is similar to a Basic mapping in the physical aspects. However, it's fetch
 * type is not configurable and it can be decorated directly with a table and sequence generator for
 * its column.
 * <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>
