If my parser tells your ContentHandler that there is a namespace,  
then there is. Your ContentHandler doesn't get to see any source bytes.

If my parser gives your code a XOM tree with namespaces, then there  
are namespaces. Again, your code doesn't get to see how the  
namespaces ended up there.

There are no namespaces in any text unless a parsing spec creates  
such a notion.
