I've been thinking of doing something similar for 
the logic rules associated with business objects.  
For example, consider an Employee class where the 
logic to calculate the bonus is based on some of the
other attributes of the object (i.e. jobcode, location).

It would be useful to define these rules in XML to 
facilitate maintenance as you point out for validation
rules.
