[Axis2] What is the purpose of the targetNamespace?

[Ryan Nelsestuen]

In org.apache.axis2.receivers.RawXMLINOutMessageReceiver.
invokeBusinessLogic, there is code that adds a namespace:

 

result.declareNamespace(service.getTargetNamespace(),

                            service.getTargetNamespacePrefix());

 

What is the purpose of that namespace?  I don't think it is used in the rest
of the document (at least, not in my case).  is it part of some standard?
