+The header `<boost/core/serialization.hpp>` implements primitives
+that are necessary to implement Boost.Serialization support without

+`core_version_type` is a Core reimplementation of
+`boost::serialization::version_type`, needed to call ADL serialization
+primitives such as, for example, `load_construct_data` below.
+
+It's defined in the `serialization` namespace instead of the `core`
+namespace because its only purpose is to add `boost::serialization` to
+the list of the associated namespaces of the corresponding call.
