  - XML schema seems to use a different canonical format, we
    need to take a closer look how to define the canonical format
    given that a date really identifies a 24 hour interval and
    what XSD means with 'interval midpoint'.

  - Shall we make the timezone offset optional? The timezone offset is
    optional in XML schema. There is CBOR work in progress to define a
    date without a timezone. The downside of optional timezones is
    that two systems in different timezones may assign different dates
    to the same event. On the other hand, there may be use cases where
    the timezone is implicit.

  - Proposal: Make the timezone optional (adding text describing the
    implications, i.e., comparisons may be surprising). Align as much
    as possible with the XML schema definition concerning the
    canonical format.
