DeviceDerivedAttribute.name

Name is the identifier for this derived attribute, used in constraints. It must be a DNS subdomain followed by a slash ("/") followed by a C identifier (e.g. "example.com/numaNode" or "derived/numaNode"). If the chosen name matches an existing physical attribute from a driver, the derived attribute's expression will shadow the physical attribute, and its evaluated value will be used in constraints instead. When the goal is to define a derived attribute that is only used within the ResourceClaim and not meant to shadow an existing attribute, use a domain prefix that no DRA driver should be using (e.g. "derived/myAttribute"). It is not valid to define a derived attribute that isn't used in at least one constraint.
