Richard,
Good point. To take this idea one step further, you can build sequences of
key/value
pairs and pass those through the IDL. That way you don't have to recode (or
regenerate)
the IDL when you modify the interface.
To go even further than key/value pair one could represent more complex
structures
using XML ( I think this was already suggested in this thread...).
