How to find the "foreign key" field name on a nested TClientDataSet?

Given a nested TClientDataSet, how could I find the link field name on the detail TClientDataSet?

I'm copying data from one TClientDataSet to another (record by record) and I would like to automatically ignore the link field.

I could also copy the data using the TClientDataSet.Data property but I still would need to clear the link and key fields.
