? What's wrong with XHTML? <img /> is clearer than <img> for anyone familiar with XML, and XHTML documents are easier to parse (e.g. can be processed with XSLT stylesheets).
Can't stand "<bla />" though with that pointless/clueless space. The only place where I've encountered these are older JSP, FreeMarker, or Thymeleaf/Spring MVC apps (ugh).
