92 92  When we zoom in on the filter component we see a simple SpEL expression that checks the value of a certain property.
93 93  When the value of the property is true the message can pass. If the value of the property is any other value the message will be halted.
94 94  The best practice would be to work with false to get clarity on what the intended use of the property value is.
