Hi,
The first thing that comes to mind is to create a Custom Provider for this. Almost every API method of a Custom Provider takes an NdProviderContext as a parameter, and the NdProviderContext will give you access to the instantiation model (the XML structure of your table/repository entry).
For validation, you could then inspect the table to check for duplicates in the provider.
To "enable" this kind of checking, you could create a column with a value holder where the value holder type is your custom provider. Alternatively you could add the value holder to an existing column definition.
