This is to allow for data that can only be edited in the ephemeral datastore
instead of running or ephemeral datastore.  It allows the XPath (and other
rules)
to be different than the existing rules for the running datastore.

My slide did not go as far as Jeff wanted wrt/ allowing ephemeral data
to reference operational data, but I think this would be OK.

As Jeff pointed out, the ephemeral data does not exist until
a controller creates it, unlike the persistent config that will be
applied at boot-time before the operational state exists.
