I agree that
leaf datastore {
type ds:datastore-ref;
description "The identity of the datastore for which
the instance data is documented for config=true data nodes.
The leaf MAY be absent in which case the running dtastore or
if thats not writable, the candidate datastore is implied.
For config=false data nodes always the operational
data store is implied.";
}
is pretty confusing. It should be something like this:
leaf datastore {
type ds:datastore-ref;
description "The identity of the datastore holding
the instance data. If the instance data is not associated
with a datastore, then this leaf MUST be absent.";
}
I am against merging data from different datastores together, which
the last sentence of the original text seems to imply.
