This is issue zoneid-48 at
http://www.w3.org/International/iri-edit/Overview.html#zoneid-48.

Margaret Wasserman, in her 'discuss' at
https://datatracker.ietf.org/public/pidtracker.cgi?command=print_ballot&ballot_id=737&filename=draft-duerst-iri,
brought up the question of how IPv6 Zone IDs would
be represented in IRIs. After detailled discussion involving several
members of the IESG as well as several other experts, I think the
following were the conclusions we arrived at:
[please don't ask me what Zone IDs are :-]

1) This is an issue that affects both the URI and the IRI spec, and
    should be fixed in parallel.
2) Given that use of Zone IDs will be rare (even rarer than use of
    IPv6 literals in general) in URIs and IRIs, and given that
    the IESG has already approved the URI draft, it seems unreasonable
    to hold back these drafts.
3) To make clear that Zone IDs are not handled (directly) by the current
    syntax, a sentence should be added to both the URI and the IRI draft
    to say so. Such a sentence will be added (as far as I understand)
    during the "Author's 24 hour review" period for the URI draft.
    For the IRI draft, I have added the sentence "This syntax does not
    support IPv6 scoped addressing zone identifiers." at the end of
    section 2.2. This tentatively closes this issue as far as this draft
    is concerned.
4) Even though the use of Zone IDs in URIs/IRIs shoud be very rare,
    because Zone IDs are really local to a specific machine, there are
    possible usage scenarios, in particular for configuration and network
    management, that make it worthwhile to define a syntax for Zone IDs
    in URIs/IRIs.
5) A new Internet Draft is being written by Bill Fenner and me to
    propose a syntax for Zone IDs in URIs/IRIs. We haven't figured
    out every detail yet, but I expect a submission soon. The basic
    idea of the draft is to use the IPvFuture production, which would
    lead to e.g. http://[v6.fe80::1234_1]/path/file.html.  The main
    technical detail to be resolved is the choice of separator for
    the ZoneID. The above example uses an '_'. I expect that we will
    announce this draft on uri@w3.org, but not on this list, because
    it is a generic URI syntax issue.


Regards,    Martin.
