This is the object's relative name (Rn) — just the last path segment of its Dn, the piece this ServerParam instance contributes to its own address within the MIT tree. It holds the actual configured limit behind a server capability — for example the maximum number of vNICs a stateless-computing feature permits per blade — separately from the feature record's name. For this kind of object the Rn is typically built from the same identifying value as its Dn's final segment, e.g. the tail end of `sys/chassis-3/blade-2/server-feature-stateless/param-max-vnics`, so two sibling instances never end up with colliding addresses under the same parent.
