  (sl. 10-18)

    some issues to decide on:
    - #35: keep infinity included
    - 0.00 -0.00 : no opinion from the wg (so do as implementers say and do not
    have both) - #37: not strong opinion - IANA: spec required but additional
    guidelines to expert - IANA: 1+2 range: add spec required

    - issues: https://github.com/cbor-wg/CBORbis/issues
        - 36: change to self-described
        - 38: fix the text that is too hard
        - 29: requires some analysis, maybe 2 solutions (1 for base64 and one
        for base64url) - Paul thinks we don't need to specify this: "you might
        do this" we don't need interoperability for tags - Chris Lemmons (+1
        from Alexey) good with interoperable tags, AP Carsten: post to the
        mailing list - 25: Carsten thinks changing terminology is not a good
        idea now. Laurence would like to change map key for label. Carsten: map
        key are not only labels. - Laurence on canonicalization: would like
        some motivation about why it exists, why and when you might want to use
        it. AP Laurence: write proposal (wg seemed to think that is a bad idea,
        more confusing) - AP Carsten: check #21 and see if it was done - 16:
        examples in the spec: add a pointer to cose github - 3: check with
        Jeffrey to see if he is satisfied - pull requests: AP authors: check
        that what was included is ok with Jeffrey
