The next patch uses these names for notifications and patch 9 for the
action. The YAML spec should contain basically this same info.
Not sure why the spec ended up with two different nests.
Just translate this enum into YAML:

    name: module-fw-flash
    attributes:
      -
        name: header
        type: nest
        nested-attributes: header
      -
        name: file-name
        type: string
      -
        name: password
        type: u32
      -
        name: pad
        type: pad
      -
        name: status
        type: u8
 ...

And you can use this nest in multiple operations, using the attributes
members of the operation to narrow down which members will show up
in given op.
