trivial question of the day. When you want your clojure keywords to also be aws tags, do you write the tag name with the colon or without? ie ":x.y/z" or "x.y/z". Or is attempting to treat tags and keywords interchangeably not worth it and it's best to just use strings in clojure (though you still might want a hand rolled namespacing mechanism anyway, so what would you use for that?)
