Yes, except you forgot that every element has a namespace node that
corresponds to the "built-in" xml: prefix which maps to namespace uri of
"http://www.w3.org/XML/1998/namespace": 

|__element (expanded-name: 'doc'+nullURI)
    |__namespace xml='http://www.w3.org/XML/1998/namespace'
    |__text '\n   '
    |__element (expanded-name: 'myElement'+'uri0')
    |   |  |__namespace xml='http://www.w3.org/XML/1998/namespace'
    |   |  |__namespace default='uri0'
    |   |  |__namespace 'foo1'='uri1'
    |   |  |__namespace 'foo2'='uri2'
    |   |  |__attribute 'id'='1'
    |   |__text '\n     '
    |   |__element (expanded-name: 'bar'+'uri0')
    |   |   |  |__namespace xml='http://www.w3.org/XML/1998/namespace'
    |   |   |  |__namespace default='uri0'
    |   |   |  |__namespace 'foo1'='uri1'
    |   |   |  |__namespace 'foo2'='uri2'
    |   |   |__text 'hello world'
    |   |__text '\n  '
    |__text '\n'
