COMMENT:
----------------------------------------------------------------------

Hi,

Thanks for these simple CBOR date definitions.

I have a couple of minor suggestions related to the use of negative integers. 
Feel free to take them or leave them:

The abstract states:

It also defines a CBOR tag for days since the date
   1970-01-01 in the Gregorian calendar for applications needing a
   numeric date representation without a time.

Given that a negative value is allowed, would it be better if this was written
as "... for the count of days relative to the date 1970-01-01" rather than "for
days since the date 1970-01-01"?  Or alternatively, possibly "since" could be
changed to "before or since".

1.  Introduction

I find the wording of "unsigned or negative" to be slightly jarring, presumably
written this way to include 0 in the set of allowed values.

  This specification also defines a CBOR tag for an integer
   representing a date without a time.  The tagged integer is an
   unsigned or negative value indicating the number of days since the
   Gregorian calendar date 1970-01-01.

The document might be more clear if it was written something like:

   This specification also defines a CBOR tag for an integer
   representing a date without a time.  The tagged integer, which
   may also take a negative value or 0, indicates the number of days
   since the Gregorian calendar date 1970-01-01.

If you decide to change this then I would also recommend changing this in
section 2.1, e.g., to something like:
   o  Tag: 100 (ASCII 'd')
   o  Data Item: Integer.  Positive, negative, or 0.
   o  Semantics: Number of days since the epoch date 1970-01-01
   o  Reference: [[ this specification ]]

Regards,
Rob
