19 * Created delegating writer to special-case error-info as error-info is defined as an empty container in the restconf
20 * yang schema but we create a leaf node so we can output it. The delegate stream writer validates the node type against
21 * the schema and thus will expect a LeafSchemaNode but the schema has a ContainerSchemaNode so, to avoid an error,
22 * we override the leafNode behavior for error-info.
