  Diffo - TMF Service and Resource Management with a difference

  LocationPoint - the lat/long where a service is delivered.

  The point is the anchor: it is always present and is what service
  qualification runs against (which CSA's bounds contain it). A postal
  GeographicAddress is a separate, optional concern — non-premise NBN
  locations (a street cabinet that needs comms but has no postal address)
  legitimately have only a point.

  A TMF675 GeographicLocation (a `location` point), in the NBN domain so it
  can carry consumer-specific richness later.
