Hi Kent,

thank you for your comments!

Regarding example, yes, I agree, we need to add examples and will do so 
in the next revision.

Per your suggestion, I looked again at the 103 minutes. They do state 
that we should come up with a single format, hence the option to select 
from different formats has been removed.    Now, which specific format 
to select is the topic of the discussion items in the Juergen's and 
Andy's emails from Nov 6.  This concerned the question whether the diff 
was to be computed against the tree, vs a textual representation of the 
tree, and if the latter, what the serialization would be. If I interpret 
the sentiment in those emails correctly, the sentiment is that the diff 
should be computed against the tree.  This is what is reflected in the 
current revision; the representation of differences leverages YANG-Patch 
(RFC 8072) and the "source-value" element extrapolates this to include 
the source values.  Of course, we can consider alternatives; this is one 
proposal.

The other item that was raised concerns whether to include diff'ing on 
metadata.  Whether this is needed probably requires further discussion.  
Personally, I think this is a useful feature but it has not been 
included in this revision.
