This is the dn of a DowngradeConstraint object, per its own definition — a capability-catalog record specifying a minimum version below which a component's firmware may not be safely downgraded. The dn ties this specific downgrade restriction to the exact component or firmware type it governs, which matters because different hardware components can have entirely different minimum-safe-downgrade versions. A dn under a specific firmware-type branch of the capability catalog's downgrade-constraint section identifies the restriction rule for that one component type, separate from a rule governing a different component.
