Yes. I think I requested this before. There should be a way to indicate
which datastore instance-data belongs to.

I also do not understand why we have instance-data-set if the set is
limited to exactly one instance-data element. Perhaps room to find a
better name for the outer container or the anyxml (perhaps change
instance-data-set to instance-data and instance-data to simply data).
Or alternatively allow multiple instance-data portions but then meta
data would need to be associated with instance-data and not
instance-data-set, so we would actually need another layer.

Also, given that this is supposed to be serialized in XML (or JSON I
assume), would it make sense to include an XML preamble in the
examples, i.e.,

<?xml version="1.0" encoding="UTF-8"?>
<instance-data xmlns=...>
  <name>...</name>
  <datastore>ds:operational</datastore>
  <data>
    <yang-library xmlns="urn:ietf:params:xml:ns:yang:ietf-yang-library">
    </yang-library>
  </data>
</instance-data>
