SOAP defines the first two namespaces and refers to the second two.
These namespaces reflect how all data type definitions in SOAP are delegated to XML Schema. The SOAP Envelope namespace defines the Envelope , Header and Body element names and the encodingStyle , actor and mustUnderstand attributes. The SOAP Encoding namespace defines the Array element and the arrayType attribute used to encode Vector and Array java objects. This encoding technique is recommended for any linear list of objects. I.e. Java 2 Collection objects can and probably should use this encoding approach.
