For when you ever have links that open in a new window, it helps to have that little image, would this be appropriate: ?
<a href="#" onclick="newwindow()" rel="external"></a>
a[onclick="newwindow()"] { padding: 10px; background: url("newwindow.png") no-repeat 0 0; }
Yes, but...
The point of having rel="external" is to provide a hook for an external javascript to add the new window functionality. If you have that external script running, then having the onclick="newwindow()" in the tag is redundant. Also, you may need some new-window links to have other onclick handlers too, so you should match on one of a pattern (foo~="value").
*Also,* having the onclick encoded in the tags reduces your separation of content, presentation, and behavior. When possible, keep the event handlers in the javascript and out of the HTML.
So...
<a href="#" rel="external"></a>
a[rel~="external"] {
padding: 10px;
background: url("newwindow.png") no-repeat 0 0;
}--
