Explosive Markup Language

Here is a new potential web technology, eXplosive Markup Language, aka XML. Here's a basic example of use:

<bomb type="c4" fuselength="short">
  <shrapnel />
  <plutonium />

XML can be used with CSS to add spice to the language, here's an example:

bomb {
  display: relative;
  visibility: hidden;
  timer: ticking;

Just make sure your XML is well-formed to guarantee its usefullness. So, what do you think?
