Contraint 'Unique Value'

There are some exceptions, and they are completely normal. For instance Q331504 (main treaty) has 3 supplementing protocols (only Q15991240 exists for now on Wikidata), and the four texts have the same Registration Number 39574. I don’t know how many such exceptions there are, and consequently if it’s worth keeping this contraint. Just mentioning it for now. ~ Seb35 [^_^] 19:44, 6 July 2018 (UTC)
