What of:
- cardinality?
- max/min values?
- co-constraints?

These are not translucent in the interface, and point up the limitations of
expressing a data model as a set of object interfaces. While the line
between processing/data model is gray, there's a lot to be gained by
expressing certain constraints declaratively (in a schema, not IDL).
