Records

The record contains the serialization data in the file and additional information on how to process the serialized data. It also has a version number.

The record is a wrapper for serializable types stored in the file. The reason for having this wrapper is to be able to use a version number, so that the serialization can be revised in the future while maintaining backward compatibility.

The following sections describe the format of the supported version:
