    <p>If you think it is important to differentiate between lined vs.
      unlined minor waterways (<i>and I'm not objecting to that</i>), I
      guess the best option would be to use a specific tag (lined=* ?)</p>
    <p>IMHO relying on the tagger knowledge of the OSM dictionary
      semantic subtleties (<i>which sometimes happen to collide with
        other English dictionaries</i>) is a bit too optimistic.<br>
