[Tagging] RFC - A broad look at fountains

[stevea]

I love reading about all the German flavors here — and I'm not a bit surprised (as the German language loves to do this, and I love German for this!)

Yes, taps CAN be drinking water, but not necessarily are.  For example, a hose_bib on a residence's "backyard porch" might be designed to attach a hose and water plants with a sprinkler or a hand-valve sprayer, but such a tap can also be declared "drinking water" (as it comes from the same source as drinking water taps indoors, often from municipal "treated water" — to make it drinkable — sources).

Yeah, there seems to me (as I consider German, Italian, English, Polish, others...) many of the perspectives from the worldwide envelope we want to use to enclose this tagging, there will be a small number of primary / main tags (one or two, maybe three at most) and a whole host of secondary tags.  That's the tough part, selecting which are which, but I don't think we want a gigantic proliferation of primary / main tags.
