text: Right - strictly speaking, that is correct. But practically speaking I think this node's amenty is "drinking_water", and the first and generally main/sole information users get is based on that (i.e. pictogram). I think the amenty should rather be "fountain" here. (http://wiki.openstreetmap.org/wiki/Tag:amenity%3Ddrinking_water : "Drinking water is a place where humans can obtain potable water for consumption"; "amenity=fountain is a fountain [for] used for cultural, decoration and/or recreational purposes."
