This is the Relative Name of the ImporterFsmStage object, distinguishing one stage of the import workflow from its sibling stages under the same ImporterFsm. An administrator uses it, together with the parent FSM path, to tell the stages of a single import's workflow apart from one another. For example, since a restore workflow may pass through several sequential stages, the RN lets an admin identify which stage entry corresponds to the file-transfer step versus the configuration-apply step.
