I'm not impressed by any of the options, but I think the erratum is
the least bad.
So....
(b) The erratum I-D [1] is the way to go, but needs work.
(Then specify your changes in "NEW"/"OLD" style.)
OLD:
... permitting a person, role or organization that owns the signing
domain to claim responsibility
NEW:
Either
... permitting a signing domain to claim responsibility
or
... permitting a person, role or organization that owns the signing
domain to claim responsibility, either directly or via a proxy to
whom
they have delegated that authority.
I don't have any strong emotional attachment to this change, and would
be content to be counted as (a) if nobody else considers this change
worthwhile.
Cheers,
Steve
