Perhaps we are less precise on that point. Actually, we are aware of the fact that drafting questions for possible use in the census is technical. The question that we are presently trying to answer is quite complicated. The technical drafting must be based on a legal appreciation of the definition of the term “rights holder”. The legal basis is perhaps not exactly the same in all national contexts. The question may well be difficult and very complicated to draft; it may contain different elements or require different data. What we are asking may well be technical and difficult, we acknowledge that. That said, it is not really our job to determine all the details and to know how to deal with those questions. The data provided could still be useful. That's why it is our sincere wish for it to be dealt with by professionals.
