-   * across different builds with schema changes due to unknown fields. Users who need canonical
-   * serialization, e.g. persistent storage in a canonical form, fingerprinting, etc, should define
-   * their own canonicalization specification and implement the serializer using reflection APIs
-   * rather than relying on this API.

-   * <p> Once set, the serializer will:  (Note this is an implementation detail and may subject to
-   * change in the future)
-   *
-   * <ul>
-   * <li> sort map entries by keys in lexicographical order or numerical order. Note: For string
-   *     keys, the order is based on comparing the Unicode value of each character in the strings.
