Then you'll have to use the XML variant and the XML MIME type.

(Similarly, if you want to use JavaScript code snippets, you have to use 
JavaScript and can't use, say, C++ or VBScript.)

The only ways to use namespaces outside of HTML right now with HTML5 DOMs 
is to either use the XML serialisation, or use a lot of very verbose 
JavaScript with DOM manipulation.

Namespaces aren't supported by the "tag soup" processors. If you want to 
use namespaces, you have to use XML.
