Question about targetNamespace

[Albert Steed]

Hello I have the following xml:

<definitions 
name="HelloWorldService" 
targetNamespace="http://hello.org/wsdl" 
xmlns:tns="http://hello.org/wsdl" 
xmlns="http://schemas.xmlsoap.org/wsdl/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
.....
.....
</definitions>

What does "targetNamespace" means?? How does it relate to "xmlns" and "xmlns:tns"? What are they for?

Thanks in advance,

Albert.
