This is a small change moving the uniqueness check of the metadata fields to Schematron.
I created a new rule called nordic_1. Maybe this number is already used, then we will change it, but validating unique fields in any order is not allowed in RelaxNG.
I did a quick check if I could add the Schematron rules as an extension of the RelaxNG rules. Seemed not to work so to be careful I created a new rule.
