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.
