Annotation that can be used to explicitly define custom resolver
used for handling serialization and deserialization of type information,
needed for handling of polymorphic types (or sometimes just for linking
abstract types to concrete types)


NOTE: since 2.4, applicable to properties as well (should have been long time
 ago, but problem only found then)
