But it isn't. The syntax for HDR becomes, in effect:

    "HDR" (header-name / ":" metadata-name) (range / "<" message-id ">")

This allows servers to support any metadata they like.

Similarly, the syntax for the LIST OVERVIEW.FMT response becomes:

    header-name ":" ["full"] / ":" metadata-name

[If you want full consistency, allow HDR to take an optional ":" or ":full"
after the header name, the latter asking for the header name to be included
in the response. I'm not proposing that, though.]
