This DHTML renderer for OPML files was largely built as a way to explore a new form of hierarchy navigation, an alternative to the standard tree widget.
It's primary advantage stems from the increased target size of the expand/collapse operator and the continued presence of the collapse option even when the parent node is scrolled offscreen.
Mission: This work was originally created to tap into the "instant outlining" features in Radio Userland. It is part of a larger work by Andy Edmonds on methods for browsing, navigating, and selecting from hierarchies. For work with cascading menus, see the exscade lab

This system reads OPML files from a web based location and turns it into a expandable/collapsible rendering.
There's a little bit of server side tracking of the dis-used instant outline update XML feed. A rewrite to work around that outage is coming.
