So it looks like we want a system that presents a general navigation path unless there is a specific application need for a more specific solution.
That is, a template designer could call breadcrumb_trail "" and get
something based on the site map or URL path. Or they could enter something more specific to the application. I can't see any other way to produce this specific to the application without having it coded into the tcl/adp pages. I can imagine a system that packages can register a page-flow into the database or something, but that seems like a little overkill.
