Indicates that the Camel language/expression should be used as predicate.
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.
Being able to distinguish between these two situations can be of importance to tooling.
