Namespaces in XML, possible error candidate

Hi, specification writers,


probably my confusion may be caused because I did not understand fully the specification (refers to http://www.w3.org/TR/REC-xml-names) or because there may be an error:

The second provided example in the section "5.3 Uniqueness of Attributes" for uniqueness of attributes refers to identic namespaces. 
<!-- http://www.w3.org is bound to n1 and is the default -->
<x xmlns:n1="http://www.w3.org" 
   xmlns="http://www.w3.org" >
  <good a="1"     b="2" />
  <good a="1"     n1:a="2" />
</x>
What is the associated namespace of the first attribute "a" in the second <good .../> element? Probably the default namespace:  xmlns="http://www.w3.org". This namespace is identic with that one defined by "n1". 
Is this really intended? If yes, why? Then you have two attributes which are identic because they are associated to the same namespace!

I would be very happy to get a feedback which resolves my misunderstanding, confusion, or questions.
