I have client specific overrides for business rules. We run the industry standard & compliance related rules first and then the client specific rules. We are currently having main biz class having the standard rules and client specific rules as a decorator over that. Then we detect the client id passed and load the appropriate decorator. Assets are loaded through a CMS due to different branding elements.

Currently I am trying to incorporate the person user control as collapsible to show hide children. Also to show person's detail on mouse hover.
