It appears I was too hasty about dismissing the reach argument. Yes, that makes sense Colin. And Joseph's suggestion to make it more general sounds good too. I think the name part needs to be set up to distinguish the name of the bend or reach from that of the river because both are valid for any section. The hierarchy below would fill the bill and more than satisfy my sense of orderliness. LOL
waterway=river name=Tanana River waterway=section section=bend section:name=Harper Bend I like what we've come up with so far. Any more suggestions?
