For a simple devices, it may be desirable to have just one schema that applies to all datastores. There is no requirement to break things apart just because there is a module that contributes only an empty set to conventional configuration datastores. > > > > Note that the defined term is 'conventional configuration datastore' > > and not 'conventional datastore'. Oops, I see that in one place draft-ietf-netconf-rfc7895bis-06.txt missing the 'configuration' part of the term.
