Minecraft 1.11 just came out. With it, a new item was added: Exploration maps.
The only thing I know about them so far is that they can be used to find a woodland mansion or an ocean temple, and can be bought from a villager. The minecraft wiki knows about the same, so I'd like to know:
Can the map be obtained elsewhere than from a villager?
What's the cost of the map?
Mainly, how can the map be used to find a structure?
