What constraint should be applied if target should have property with one of several predefined (say 2 different) values? Infovarius (talk) 18:44, 7 July 2013 (UTC)[reply]

Check a class of the value[edit]

Support sub/parent classes of values.

In interplanetary spaceflight (Q834235) we have to enumerate all planets, simpler constraint would help. d1g (talk) 09:23, 1 January 2017 (UTC)[reply]
