| * The {@link ExpressionVisitor} that adds support for the additional JPQL identifiers supported by |
| * EclipseLink that is not defined in the JPA function specification. |

| * <b>Important:</b> If a new specification of the Java persistence is released, this interface will |
| * be augmented to support the new functionality. |
| * <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. |
