This holds the rn — the Relative Name — of the capability-catalog override rule that changes how UCS Manager's hardware-discovery logic classifies or constrains one specific DIMM part during blade inventory; it is only the final path segment identifying this object relative to its immediate parent, not the whole dn. Because a memory discovery-modifier rule is nested under a parent object in UCS Manager's tree, the rn is what distinguishes it from sibling entries under that same parent without repeating the full ancestor path every time. For an object whose dn is 'capabilities/mem-mod-1', the rn would just be the trailing segment 'mem-mod-1'.
