I didn't like the way rivers look in worldoutlines, so I made them look the way they look when generated by river2.root. Instead of rendering in the template for the world outline, they render in the beautiful river template, exactly.
On your server, update both beaut.root and worldOutline.root.
View a river node.
Does it work? Does it look like the rivers that are produced by river2.root?
If you add attributes to the river nodes called description and opmlUrl, they will appear correctly.
Otherwise they will be blank.
