One thing I forgot to mention during the discussion today: CalConnect was
planning on a registry of timezone names but we wanted to have these as
urns, probably urn:tzid:XXX etc. I think this is a reasonable use of urns
and provides a way to unambiguously indicate the scope of identifiers we
So if we choose to adopt this approach, the TZ document would need to
register the new urn scheme, and then define the tzid registry where one of
the attributes of the registry is the timezone's urn identifier.
