The namespace declaration here is wrong. It should be: 
http://www.w3.org/2001/XMLSchema

Again, the namespace declaration here is wrong. It should be: 
http://www.w3.org/2001/XMLSchema-instance

If you change the namespace declarations it should work fine.

The reference to w3.org is only there to say that the schema you have 
defined is a W3C XML Schema and the parser won't connect to the website 
so you don't need a network connection to validate the above example.
