Med: "metric-unit": What if the unit does not comply with the metric type? Ex. delay + unit=byte or mbps? Why not defining those as identyrefs? "bound" default: Do you really need this. Please note that FC8407 says: "The following guidelines apply to reusable groupings, in order to make them as robust as possible: ... Do not include a "default" substatement on a leaf or choice unless the value applies on all possible contexts."
