I have tried the following with Firefox, Opera, IE, Safari, and Chrome. 
  Given that each show the attribute, that is the one thing I don't 
expect to change.  As to the spec, perhaps you are right and it may 
permit others to not interoperate with browsers and still claim to be 
conformant.

<html>
<head>
   <title>test colon in attributes name</title>
</head>
<body>
<ul id='list'></ul>
<script>
var list = document.getElementById('list');
list.setAttribute('xmlns:dc',
   'http://dublincore.org/documents/dcmi-namespace/');
var attrs = list.attributes;
var length = attrs.length;
for (var i=0; i<length; i++) {
   var value = attrs[i].nodeValue;
   if (!value) continue;
   value = value.replace(/&/, '&amp;').replace(/</, '&lt;').
                 replace(/>/, '&gt;').replace(/"/, '&quot;');
   var li = document.createElement('li');
   var text = document.createTextNode(attrs[i].nodeName+'="'+value + '"');
   li.appendChild(text);
   list.appendChild(li);
}
</script>
</body>
</html>
