The DeltaSpike sometimes requires to create new annotation. There are "parameter binding annotation" and "security binding annotation" in security module (doc). If the anotation haven't this repention policy,then the annotation doesn't works (explanation).

This is a valid annotation

@Retention(value = RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
@Documented
@SecurityBindingType
public @interface CustomSecurityBinding {
}

and this doesn't work

//@Retention(value = RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
@Documented
@SecurityBindingType
public @interface CustomSecurityBinding {
}

I am not sure if that can be or should be validated.
