I have no idea how namespace prefixes would work in an HTML parser.  
Perhaps you can take a look at  
http://www.whatwg.org/specs/web-apps/current-work/#parsing and see what  
might need to be done to make that namespace prefix compatible? I  
personally don't really see value in adding any kind of namespace syntax  
to HTML.

Note that you can't rely on well-formedness in the parser and that you  
need to handle all error cases as well in a way that doesn't cause a  
"yellow screen of death" to be generated.
