The description of the "datastore" leaf doesn't make much sense to
me. It says that for configuration data the default is "running" or
"candidate" if "running" isn't writable. Why should it matter whether
"running" is writable? It looks like it is assumed that the config data will
eventually be fed into the indicated datastore, but I don't see any
reason for such an assumption.

I can see that "datastore" can be occasionally useful as auxiliary
metadata but, in my view, this document addresses also instance data
that is not necessarily bound to any datastore.
