Serialization Events [Serializing], [Serialized], etc

It looks like Serialization Events [Serializing], [Serialized], [Deserializing], and [Deserialized]
were not applicable in .NET Framework 2.0 for a SoapFormatter serialization according to my MCTS 70-536 App Development  .NET Framework Foundation book. It says only BinaryFormatter Serialization can use Serialization attributes [Serializing], [Serialized], etc.

The question is what version of .NET Framework was SoapFormatter Serialization able to use Serialization Attributes [Serializing], [Serialized], [Deserializing], and [Deserialized]?

the following classes were introduced in .net 2.0 and supported by SoapFormatter:
OnSerializedAttribute
OnDeserializedAttribute
OnDeserializingAttribute
OnSerializingAttribute

if you run the code below, u see that all serialization attributes are being supported and added to the static events list.

check this code:
[Serializable]
    public class SoapFormatterTest
    {
        //store serialization events
        public static List<string> events = new List<string>();

        [OnSerialized()]
        internal void OnSerialized(StreamingContext context)
        {
            events.Add("OnSerialized");
        }
        [OnDeserialized()]
        internal void OnDeserialized(StreamingContext context)
        {
            events.Add("OnDeserialized");
        }
        [OnSerializing()]
        internal void OnSerializing(StreamingContext context)
        {
            events.Add("OnSerializing");
        }
        [OnDeserializing()]
        internal void OnDeserializing(StreamingContext context)
        {
            events.Add("OnDeserializing");
        }

        public string Name = "SF";
        private int ID = 1234;
        public Hashtable addresses = new Hashtable();

        public SoapFormatterTest()
        {
            addresses.Add("Jeff", "123 Main Street, Redmond, WA 98052");
            addresses.Add("Fred", "987 Pine Road, Phila., PA 19116");
            addresses.Add("Mary", "PO Box 112233, Palo Alto, CA 94301");
        }

        public void Deserialize()
        {
            FileStream fs = new FileStream(@"c:\temp\DataFile.soap", FileMode.Open);

            SoapFormatter formatter = new SoapFormatter();
            try
            {
                SoapFormatterTest instance = (SoapFormatterTest)formatter.Deserialize(fs);
            }
            catch (SerializationException e)
            {
                Console.WriteLine("Failed to serialize. Reason: " + e.Message);
                throw;
            }
            finally
            {
                fs.Close();
            }
        }

        public void Serialize()
        {
            FileStream fs = new FileStream(@"c:\temp\DataFile.soap", FileMode.Create);

            SoapFormatter formatter = new SoapFormatter();
            try
            {
                formatter.Serialize(fs, this);
            }
            catch (SerializationException e)
            {
                Console.WriteLine("Failed to serialize. Reason: " + e.Message);
                throw;
            }
            finally
            {
                fs.Close();
            }
        }

    }

        {
            SoapFormatterTest sf = new SoapFormatterTest();
            sf.Serialize();
            sf.Deserialize();
            foreach (var ev in SoapFormatterTest.events)
            {
                Console.WriteLine(ev);
