Meta-annotation that commands the compiler plugin to handle the annotation as serialization-specific. Serialization-specific annotations are preserved in the SerialDescriptor and can be retrieved during serialization process with SerialDescriptor.getElementAnnotations for properties annotations and SerialDescriptor.annotations for class annotations.

It is recommended to explicitly specify target for serial info annotations, whether it is AnnotationTarget.PROPERTY, AnnotationTarget.CLASS, or both. Keep in mind that Kotlin compiler prioritizes function parameter target over property target, so serial info annotations used on constructor-parameters-as-properties without explicit declaration-site or use-site target are not preserved.
