This is true in XML, but that's not the case in Selectors, and it's not obvious 
that it should be true for this API.

For example, the following document:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
   <style>
     html { color: red; }
     html[xml|lang="en"] { color: green; }
   </style>
</head>
<body>
Text
</body>
</html>

Gives me red text and a CSS parse error complaining about an unknown namespace 
in both Gecko and Presto.
