The matter is that the code presented by the help page requires an onClick attribute, which is actually deprecated in XHTML.

To overcome this problem here is a simple jQuery plugin which converts any rev (or other given) attribute to a Google Analytics friendly tracking path (for both old and new versions of the app). Here is a sample code:

<a href="http://www.externalwebsite.com" rev="outbounds www.externalwebsite.com">visit this site</a>

Is tracked as /outbounds/www.externalwebsite.com

To apply this plugin call it inside a document loaded function, for example:

$("a").colt();

This calls the plugin on all A tags with an attribute rev.
Moreover you can use a custom element attribute by just passing it to the function:

$("a").colt("title");

And finally here is the source code:
