When you define a layer rule for a widget you can set a url like
which would match /foo/bar/baz, but not /foo/bar
The "path" attribute" of the "match" element in placement.info however (path="/foo/bar/*") would match both
/foo/bar/baz and /foo/bar
To me it doesn't make sense /foo/bar/* to match /foo/bar because there is no trailing "/". If I needed this I would go with /foo/bar* (note that there is no '/' before the *). That's how would a reg ex work too.
