The Typed Name syntax has three fields: entry ID, level, and interval. The partition operation (PC_IDLE, PC_JOINING_UP, PC_JOINING_DOWN, PC_MOVE_SUBTREE_DEST, PC_MOVE_SUBTREE_SCR, etc.) is stored in the level field. The partition state which uses the same values defined for replica states is stored the interval field.
