mahau,

I am thinking of reworking Sungai Perak. I found that the watershed relation confusing, and the waterway multipolygons are not closed. Would it be easier for everybody to understand if we redo them in smaller chunks of simple multipolygons? i.e role outer, waterway=river; role inner, natural=scrub/place=island. Maybe in a year or two, we can consider adding other types of waterway relations…
