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

Thanks for your work on this spec. Thanks also to Kent Watsen for his hard
work shepherding it.

I have some comments below which I hope may be helpful.

1. Section 1, nit, s/In Appendix C describes/Appendix C describes/ (delete
the
"in")
BALAZS: OK, will be updated

2. Section 1.4:

   A YANG instance data set is created at a specific point of time.  If
   the data changes afterwards, this is not represented in the instance
   data set anymore.  The current values may be retrieved at run-time

I think "anymore" should be cut, for several reasons, the most important of
which is that it seems to be objectively wrong. The cut would be the minimal
fix, but did you mean something more like this? "If the data changes
afterwards, the instance data will no longer represent the current data,
unless it is updated."
BALAZS: OK, will be updated with the additional text. 

3. Section 2, nit, s/constrains MAY be violated/constraints MAY be violated/
BALAZS: OK, will be updated

4. Section 2.1: I was amazed that the "external method" option, which is
essentially the "simply don't bother" option, was acceptable to the WG and
other reviewers. To my eye, the URI method option seems functionally just as
good (it keeps the content of the file itself small) while providing a
stronger (though still not very strong) assurance that the schema will
actually be available.
   Was "external method" discussed in the WG? Or am I simply in the rough
for even thinking it surprising?
BALAZS:  People stated that when instance files are used repeatedly (a new
file
        generated every few seconds) in a closed, well defined environment,
the
        content-schema may already be known. In this case it is not
necessary to
        include it in the file.

5. Appendix C: I'm inclined to agree with the shepherd's recommendation to
remove this entire section
(https://mailarchive.ietf.org/arch/msg/netmod/5DfEi8swOmLEPykBpFICJK6398s/)
since readability is problematic and it doesn't seem to add to the usability
of the spec. Since it is, as it says, only a non-normative appendix I don't
insist, but I strongly encourage you to consider trimming or rewriting it.
BALAZS: We will consider it. Some editorial updates, trimming done.
