Ins and del elements
Tom Gilder mentions ins and del elements, which I didn’t even know existed. Of course, they’re part of the spec. Interesting; a track changes function. I’ve essentially invented these tags with <span class="orig"> and <span class="change" title="01/01/2003 00:00"> in the past, but I shall switch to using the semantically correct versions. I was pleasantly surprised to see them supported by IE5.5, too.
