Annotation Interface PolymorphicConfig
This annotation marks the class as a polymorphic configuration schema. Has basically the same properties as a
Config, but it
should be treated like an abstract class in java.
To change the type of polymorphic configuration, you must use the PolymorphicConfigChange#convert.
NOTE: PolymorphicId field must be present, you should explicitly declare that, also at least one
PolymorphicConfigInstance is required.
