Interesting - how would you imagine the `functional rules' ? I would 
advise against building any kind of interpret machine into the MDR; if 
you think about some callback, that's most probably how it will be done.
Right now I am thinking about either a model method, or a derived 
association, whose implementation will call out to a metadata producer 
in the case the data won't be available. So instead of giving rules, I 
will hook in a metadata producing machine.
Ideally, a client using JMI reflection could extract that data without 
knowing they're transient.
