<img> explicitly says "The img element must be empty." in the prose. Same for <br>. This isn't done for the <base>, <link>, <meta>, <hr>, <embed>, <param>, <area>, <col> and <event-source>. (I suppose there might be others if I skipped one.) -- Anne van Kesteren <http://annevankesteren.nl/> <http://www.opera.com/>
