[Jody Garnett <jody.garnett@xxxxxxxxx>]

As a programmer you can do this see the style page in the developers

XML. For an example use the walkthrough one instructions to generate a  
theme and then use the advanced page to delete all bit one of the  
rules. And then change the rule filter to perform your test.
