Something like introducing an identity for italian-car in between car
and Ferrari identities
I understand your intention. I do not understand the intention behind
text in RFC 7950, however.
My clarification request was aimed at RFC 7950 authors and whether a
revision like this could be considered as not changing the semantics of
the original identity definition because:
Otherwise, if the semantics of any previous definition are changed
(i.e., if a non-editorial change is made to any definition other than
those specifically allowed above), then this MUST be achieved by a
new definition with a new identifier.
So, RFC authors: Is "NEWB:bar" definition semantically equivalent to
"OLD:bar" definition?

According to section 11 of RFC7950, the following change is
considered BC:
o A "base" statement may be added to an "identity" statement.
Since, as explained in section 7.18.2 of RFC7950, the derivation
of identities is transitive, my understanding is that replacing a
"base" statement with new "base" statement which is derived from
the previous one is also a BC change.
Considering the example below, the NEW (A) change is BC according
to section 11 of RFC7950. However, NEW (B) is equivalent to NEW
(A), since the new baz is derived from foo, and therefore it is
also a BC change.
Is my understanding correct?
I'd like a clarification regarding this as well. Is "NEWB:bar"
definition semantically equivalent to "OLD:bar" definition?

Thanks, Italo
OLD
identity foo {}
identity bar {
base foo;
}
NEW (A)
identity foo {}
identity baz {
base foo
}
identity bar {
base foo;
base baz;
}
NEW (B)
identity foo {}
identity baz {
base foo
}
identity bar {
base baz;
}
