If this is referring to the issue that was raised long ago regarding xmlns  
attributes in the DOM. The issue was not that they would not end up in the  
DOM. They do. This is interoperably implemented and required by HTML5. The  
issue is that they do not end up in the DOM in the same namespace as they  
do in XML. In XML xmlns attributes when added to the DOM are put in the  
http://www.w3.org/2000/xmlns/ namespace (see section 3 of /TR/xml-names).  
In HTML xmlns attributes when added to the are put in no namespace, just  
like any other attribute.

Henri explained this a lot, e.g. in  
http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-January/018242.html  
but see also the other emails in that long thread...
