The page now says, like: "... specify |from= either by Q-ID or by their label in the wiki's content (?) language".
Question 1: My tests showed that one can not specify an item by its 'label' (=the article name in the example enwiki, we understand).
<pre>
{{#property:P17|from=Italy}}
</pre>
should show {{#property:P17|from=Italy}}
Question 2: If I'm wrong (it does work well), should we remove the question mark?
(-edit-: talkpage code shows different from my habit).
