Is there a good reason that <foo /> cannot be valid HTML5? Any parser 
which doesn't support <foo /> also doesn't support much of the web 
content produced in the last 2 years. In this case a conformance checker 
could emit a warning (maybe only a strict warning) since it's not 
impossible that people will expect HTML5 to work in a parser that's 
incompatible with real-world HTML4.
