Medium Description
Parsing of Yang sources with a deviated case node fails if the case node was created with augmentation without explicit case statement.
For example, parsing of the following two modules fails.
module orig {
namespace "urn:orig";
prefix orig;
container foo {
choice bar {
leaf bar1 {
type string;
}
}
}
augment /foo/bar {
leaf bar2 {
type string;
}
}
}
module deviate {
namespace "urn:deviate";
prefix dev;
import orig {
prefix orig;
}
deviation /orig:foo/orig:bar/orig:bar2 {
deviate not-supported;
}
}
Error message says that the case node is not found:
