Re: [Cbor] I-D Action: draft-ietf-cbor-cddl-06.txt

We have submitted a version of CDDL that should address all the comments from AD review and IETF last call, including the discussions at the Bangkok IETF meeting.

Diff is at: https://tools.ietf.org/rfcdiff?url2=draft-ietf-cbor-cddl-06.txt

Most of the changes were editorial.  A technical decision that we made at the Bangkok meeting was prompted by the Gen-ART comment number 3: the behavior of reverse ranges (e.g., 10..0) was not defined.  The text now says:

2.2.2.1.  Ranges

   Instead of naming all the values that make up a choice, CDDL allows
   building a _range_ out of two values that are in an ordering
   relationship: A lower bound (first value) and an upper bound (second
   value).  A range can be inclusive of both bounds given (denoted by
   joining two values by ".."), or include the lower bound and exclude
   the upper bound (denoted by instead using "...").  If the lower bound
   exceeds the upper bound, the resulting type is the empty set (this
   behavior can be desirable when generics, Section 3.10, are being
   used).

So, of the potential meanings of 10..0, we chose the empty set.
This is now in -06; if that is a problem for you, we would like to know about that.
