    Dbus NVMe Feature Store handles Get/Set Features for a storage resource,
    transferring raw proto binary over byte arrays.

properties:
    - name: ProtoLibraryVersion
      type: string
      flags:
          - const
      description: >
          The static version of the compiled Protocol Buffer library used by the
          nvmed daemon (e.g., "2.0"). This maps directly to the
          DataProto.Revision field in the Redfish payload.
    - name: FeatureCollection
      type: array[struct[string, string, string]]
      flags:
          - const
      description: >
          A static collection of tuples representing all supported NVMe Features
          for the component. Each tuple is formatted as [FeatureName, FeatureId,
          ProtoClassName] (e.g., ["VolatileWriteCache_Current", "0x06",
          "google.gbmc.nvme.base.VolatileWriteCache"]).

methods:
    - name: GetFeature
      description: >
          Read the data of an individual NVMe Feature directly from the device.
      parameters:
          - name: FeatureName
            type: string
            description: >
                The Identifier for the requested Feature (e.g.,
                "VolatileWriteCache_Current").
      returns:
          - name: Ret
            type: array[byte]
            description: >
                A byte array containing the raw proto binary response payload.
      errors:
          - xyz.openbmc_project.Common.Error.InvalidArgument
          - xyz.openbmc_project.Common.Error.Unavailable

    - name: SetFeature
      description: >
          Configure an individual NVMe Feature on the device.
      parameters:
          - name: FeatureName
            type: string
            description: >
                The Identifier for the Feature being patched (e.g.,
                "VolatileWriteCache_Current").

            type: array[byte]
            description: >
                A byte array containing the raw proto binary payload to apply.
