So basically, it's the same as tag soup. I don't really see an advantage 
to going down that route (with its complexities like namespace prefixes, 
etc) -- if anything, the lack of success of IE's extension mechanism 
should be taken as a sign that this is not the path to follow. (Compare 
this to, e.g., <marquee>, which was so widely used that other browsers 
were forced to support it.)
