>*  1. There is a sign that says you can drink it or it is otherwise clear that you can (drinking fountain constructed by muncipality) -> drinking_water=yes
>*  2. There is a sign that forbids it or warns that it is contaminated -> drinking_water=no
>But what about these?
>*  3. There is no sign at all and no clear indication whether it is drinkable or not. Water that comes out of a mountain might be polluted with toxic substances, especially if it is close to an (old) mine. 
>*  4. There is a sign that simply says "no drinking water" but it is clear from the circumstances that it is. Don't have a good example right now, maybe because of insurance, or nearby shop wants to sell bottled water.
>In case 3, where a surveyor cannot with certainty determine if it should be drinking_water=yes or no (without trying it himself and waiting if he becomes ill or not, which can't be expected of the surveyor). So in this case, he would need to leave drinking_water untagged. But what he can with certainty record is that there is no official information about it whatsoever. This is useful because people searching for drinkable water would certainly prefer water sources where it is positive that it is drinkable. drinking_water=unknown or drinking_water:signed=no would solve this, but there is also case 4.
>In case 4, the official information would deviate from the actual situation on-site, which could warrant to record these two informations separately when necessary.
