G'day to all!

I'm currently trying to implement some kind different kind of Lookup Values in one Table. So for instance a Currency, Country, Cities etc, etc all in one table.
Looking something like this: id, code, description, type_id where type is an id pointing to a meta lookupvalue expressing the type like Currency,
Country, City etc. I want to implement the various Lookup types as a subclass on the Master Lookup, I know I can discriminate on the value of the type, but it would be nice if I could discrimintate on the value inside the meta-lookup lookup type.
something like

regards and best wishes,
Jeroen.
