How To Use Revhistory Attribute Sets

Can someone please 
provide a simple example of how to user the revhistory attribute sets? I've been 
trying for hours and researching the web and haven't been able to customize the 
fo formatting in anyway. Specifically, I'm trying to figure out how to add a 
border to the revhistory in RTF output, but I haven't been able to successfully 
apply any kind of formatting.

 

Thanks.
