====Motivation====
We need a reason why there is no value so the next person does not waste time looking for it. I need a little help formatting this proposal.

===={{int:Talk}}====
*{{comment}} In general, I think the criteria are more similar to custom values than to ranks. Accordingly, I'd use similar qualifiers (e.g. {{P|1013}}, P828, P3831).
:I'd rather add some description to the property itself. The reasons are likely always the same for a property. 
:For P569/P570 mentioned above, I'm not sure if it's a good idea to mix novalue/unknown. These properties would use novalue only for immortals and unknown is fairly rare: generally at least the century is known. --- [[User talk:Jura1|Jura]] 09:53, 19 November 2019 (UTC)
