Purpose
Allows to check if items using a given property also use other properties.
Sample
  1. Wikimedia language code (P424) is used on items about languages.
  2. These items all should have instance of (P31) = language (Q34770).
  3. To check this and find items that still miss instance of (P31) = language (Q34770),
    add {{Constraint:Item|property=P31|item=Q34770}} to Property talk:P424.
