| * For example the EIPs which accepts expression/languages may used them as either expression or predicate. |
| * This annotation is used to mark situation where they should be used as predicate. As by default they |
| * are used as expression. And example would be the Filter EIP which uses predicate. And the transform EIP |
| * uses an expression. |
| * <br/> |
| * Being able to distinguish between these two situations can be of importance to tooling. |
