draft-ietf-netmod-yang-instance-file-format-00.txt says:
The JSON format SHALL follow the format of the reply returmed for a
RESTCONF GET request directed at the datastore resource:
{+restconf}/data. ETags and Timestamps SHOULD NOT be included, but
if present SHOULD be ignored.
I assume that you mean the JSON content in the message-body of the
HTTP Response message for GET message. My understanding is that ETags
and Timestamps (what are these precisely?) are carried in the HTTP
header. So how could the ETag or 'Timestamps' be in the JSON data? We
should not mess up the HTTP difference between header data and payload
data.
I also do not fully understand the text concerning the XML format.
The XML format SHALL follow the format returned for a NETCONF GET
operation. The <data> anydata (which is not part of the real data
itself) SHALL contain all data that would be inside the <data>
wrapper element of a reply to the <get> operation. XML attributes
SHOULD NOT be present, however if a SW receiving a YANG Based
Instance data file encounters XML attributes unknown to it, it MUST
ignore them, allowing them to be used later for other purposes.
It is unclear what exactly is the instance data - the entire reponse?
Everything inside <data>? Everything inside and including <data>? I
assume the second sentence is trying to say the later but I do not
find it very clear not does it seem to be right. The examples show to
content of the NETCONF <rpc-reply><data/></rpc-reply> inside a <data>
container that belongs to the instance data format (two times <data>
but in different namespaces).
It is also unclear to me why XML attributes are to be removed. Why is
that? If I snapshot <operational>, why should I remove important
information such origin annotations? And removing attributes is
actually plain wrong if you consider that attributes carry XML
namespaces.

PS: I am also concerned about the revision being not fine grained
enough to be useful. I would love to have a much more precise
timestamp telling me when the instance data was recorded. I would
probably replace 'revision' with simply a 'timestamp' or add next
to a 'revision' a more fine grained 'timestamp'.
