Initializes an instances of the System.Xml.Serialization.XmlSerializationWriteCallback delegate to serialize SOAP-encoded XML data.
The protected members of System.Xml.Serialization.XmlSerializationWriter are intended for use only by derived classes that are used internally within the .NET Framework XML serialization infrastructure.
During initialization, the .NET Framework XML serialization infrastructure dynamically generates and compiles a temporary class for serialization that is derived from System.Xml.Serialization.XmlSerializationWriter. During this process, the .NET Framework generates write methods that implement the System.Xml.Serialization.XmlSerializationWriteCallback delegate. It does so for certain mappings between .NET Framework types and XML data types that are serialized using SOAP-encoded XML and are not root elements. Then, as necessary, a write method is called during serialization.
The abstract XmlSerializationWriter.InitCallbacks method is where the temporary derived class creates an instance of and initializes write callback methods.
You should not directly create an instance of System.Xml.Serialization.XmlSerializationWriteCallback.
SOAP encoding is described in Section 5 of the SOAP 1.1 specification.
