I wrote a reply to Bestians message but the system ate it :-(

I argued the same way. It would be great to have the validation rules of 
Extbase "at hand" in the TCA like

"eval" => "Tx_Extbase_Validation_Validator_EmailAddressValidator"

After I read the f****** manual, a have to admit that this is already 
possible (nearly). Even the JavaScript stuff.

I agree, too. We should provide a method to easily find and adjust 
invalid existing data.
