I have a follow-up question about this topic
Considering the same identities defined below, what would be the valid values
the following references?
leaf reference-1 {
type identityref {
base base-1;
}
description
"Reference to an identity #1.";
}
leaf reference-2 {
type identityref {
base base-2;
}
description
"Reference to an identity #2.";
}
My understanding, is that:
- valid values for the reference-1 would be 'a' and 'b'
- valid values for the reference-2 would be 'b' and 'c'
Is my understanding correct?
Thanks, Italo
