| * Adapter for serializing and deserializing {@link OffsetDateTime} to and from JSON in a format compatible | ||
| * with the legacy {@code XMLGregorianCalendar} used in older versions of the library. | ||

| * date-time format while allowing migration to Java 11's {@code OffsetDateTime}. | ||
| * </p> | ||

| * <p><b>Serialization</b></p> | ||
| * The {@code serialize} method converts an {@code OffsetDateTime} object into a JSON structure | ||
| * similar to the structure used by {@code XMLGregorianCalendar}, preserving the fields for year, | ||
| * month, day, time, timezone, and fractional seconds if present. | ||
| * | ||
| * <p><b>Deserialization</b></p> | ||
| * The {@code deserialize} method converts a JSON structure formatted for {@code XMLGregorianCalendar} | ||
| * into an {@code OffsetDateTime} object, parsing the legacy fields and converting them to their modern | ||
| * equivalents, including handling timezone and fractional seconds. | ||
