I agree with Juergen, that depending on where YANG versioning goes, that 
a mechanism to provide this information is required (e.g. a list of 
modules + semvers for the schema used in the instance data).  It should 
be optional to publishers whether they populate this information.

The draft already has instance-data revisions.  I regard that as a 
mechanism for versioning instance data.  I'm not saying that this is 
necessary the right approach.

I see this "version" as file level meta-data information, in the same 
category as name, contact, description, organization meta-data fields 
that the draft currently provides.  Another field that may be 
generically useful is the time/date stamp of when the instance data was 
generated.  Although perhaps the timestamp of the file is sufficient for 
this purpose.

Thanks,
Rob
