Description
Parsing of YANG models fails if a deviation statement targets a node conditionally augmented based on a feature and the feature is not supported.
In the following example with two modules, foo & bar, parsing fails if foo-feature is not supported.
foo.yang
module foo {
namespace "urn:foo";
prefix "foo";
feature foo-feature;
container foo {
}
augment /foo:foo {
if-feature foo-feature;
leaf foo-leaf {
type string;
}
}
}
bar.yang
module bar {
namespace "urn:bar";
prefix "bar";
import foo {
prefix foo;
}
deviation /foo:foo/foo:foo-leaf {
deviate not-supported;
}
}
Parsing fails after trying to find the deviation target foo-leaf:
