Agreed. > Well, according to draft-ietf-netmod-revised-datastores-07: > > o datastore schema: The combined set of schema nodes for all modules > supported by a particular datastore, taking into consideration any > deviations and enabled features for that datastore. This text does not write that nodes with false when expressions are not considered part of the schema. > And "when" determines whether a given schema node is valid or not.

Again, it is a matter of terminology - when we say that the "schema" of <operational> is a superset of the "schema" of the conventional datastores, we do not exclude false when expressions from the "schema". As per the defintion above we include the modules, their features and deviations in the term "schema". /martin >, then the former can hardly be a superset of the latter. > > Lada > > > > > /js > > > -- > Ladislav Lhotka > Head, CZ.NIC Labs > PGP Key ID: 0xB8F92B08A9F76C67 > > _______________________________________________ > netmod mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/netmod > _______________________________________________ netmod mailing list [email protected] https://www.ietf.org/mailman/listinfo/netmod
