XHTML didn't do that at all. The only thing XHTML did was expressing the  
HTML language in XML. Since HTML was already a tree language where nodes  
in the tree have attributes this was fairly trivial.

The only thing that has thus changed is the syntax, not the language. So  
the only thing that was fixed by XHTML (XML really) was the error handling  
of the syntax (there isn't any, you get some stupid error message in your  
browser). HTML5 fixed the syntax error handling for the HTML syntax in a  
manner believed to be compatible with the web.

This still doesn't solve the problem for error handling with the language.  
What if an attribute has an incorrect value? What if an element is nested  
in an element within which it isn't allowed? For instance:

   <form action="a"><a href="b"><input type="button"/></a></form>

XHTML didn't solve that. Browsers are handling the above case also  
identically in HTML and XHTML. It makes no sense to implement such logic  
twice in incompatible ways.


Fixing the syntax of HTML is just a minor thing and has already been done  
to some degree (its even implemented and testsuites are available).
