title: Semantic mediawiki #ask query: Displaying nested properties on the same query
body: <p>I would like to display in the same query properties of a page which is related to the pages im querying for.</p>
  
  <p>Let's say I would like to query all the pages in the City category, which are located in Germany, and I want to display the title of the page, but also I want to display the surface data of Germany, for example.</p>
  
  <p>Something like this: <code>{{#ask: [[Category:City]] [[location::Germany]] |?mainlabel |?Location.surface }}</code></p>
  
  <p>I know this wont work, but you can see what I want to achieve.</p>
