 * Region Digraph should not impose a policy of always using reference: URLs.
 * This policy is further exasperated by the fact that reference: URLs only
 * work if the embedded URL uses the file: protocol. It should be up to the
 * client to decide which protocol to use. Digraph should support any URL for
 * which there is a compatible URL Handler.
