I don't understand how using namespace prefixes solves anything. For 
your example we can imagine an well-formed fragment

<x:a xmlns:x="foo:">
  <x:n/>
</x:a>
<x:a xmlns:x="bar:">
  <x:n/>
</x:a>

You still need to refer to the namespace URI (which, by the way, must 
be a URI unlike in your example) in order to differentiate the two 
instances of x:a.
