Bill,

Look into de CDE (Codemine Data Environment) of the codemine framework. It is very polished and includes the concept of reusable rule objects, that do exactly what you are planning to do. It is also tied with the valid methods of the controls, so they are called automatically by the framework at appropriate times.
