Not that I can be bothered to start counting them, but I'd submit to  
you the there is more wealth of knowledge, specialisms, areas of  
interest, etc which is being conveyed by web sites worldwide that is  
quite distinct from anything technical requiring these elements.  
Mathematics, chemistry, logic, philosophy, medicine...all these would  
also benefit from their own elements to accurately mark up their  
content, so why is it that computing technology is "built in" to XHTML  
2.0 while these others aren't? Just because "you write XHTML 2.0 on a  
computer"?
