Okay, so if I understand well, xml:lang in the spec refers to the  
"lang" attribute in the "xml" namespace, not to the "xml:lang"  
attribute in the null namespace that you get with the HTML parser. It  
makes sense from a DOM perspective, but it's misleading from a markup  
perspective, so I still think it should be clarified.

And although it's less confusing, I think the same should be  
clarified about xml:id: it's the "id" attribute in the "xml"  
namespace, not the "xml:id" attribute in the null namespace that you  
get with the HTML parser.
