Discussion

Missing use of P461 generates a lot of errors

It seems like rules demanding use of opposite of (P461) generates a lot of errors, as the opposite category very often does not exist. That would be sort of okey, but the error messages are about errors on the category pages and are posted on the location pages where this property is used. It is thus an out of context error message. Because the test is actually wrong, as it is not an error that the opposite category does not exist, I think the simplest solution would be to remove the rule completely.

I moved it down the page. After the next update of the constraints for the special page, the errors there will disappear. --- Jura 18:13, 24 July 2015 (UTC)
