namespace conformance question

["zhengyu" <zhengyu@attbi.com>]

Hi, I was reading XML namespace doc 14/Jan/99 version. One of the snippets that is supposed to be illegal seems OK with MS net explorer 6.0. It is shown below, and the bad element is named "bad."

 

<!-- http://www.w3.org is bound to n1 and n2 -->
<x xmlns:n1="http://www.w3.org" 
   xmlns:n2="http://www.w3.org" >
  <bad n1:a="1"  n2:a="2" />
</x>

 

Do any microsoft people have any explanation for this?
