This carries the relative name of the Infra object, distinguishing it from other firmware-related objects in the same catalog. Since there is typically a single Infra instance per domain, the Rn is a fixed, predictable value that mainly helps a management tool confirm it is looking at the infrastructure firmware object specifically rather than, say, a Host or Image object. The Rn here will consistently read something like 'infra-policy', identifying this row's role rather than distinguishing among siblings.
