   YangInstanceIdentifier.NodeIdentifier contId = new YangInstanceIdentifier.NodeIdentifier(QName.create(moduleQName, "example-container");
   
  -NormalizedNode<?, ?> contNode = ImmutableNodes.fromInstanceId(schemaContext, YangInstanceIdentifier.create(contId));
  +NormalizedNode contNode = ImmutableNodes.fromInstanceId(schemaContext, YangInstanceIdentifier.create(contId));

   Let us show a more complex example of creating a NormalizedNode. First, consider the following YANG module:
  
positive.code: inMemoryDataTree.commit(inMemoryDataTree.prepare(treeModification));
  
  DataTreeSnapshot snapshotAfterCommits = inMemoryDataTree.takeSnapshot();
  Optional<NormalizedNode<?, ?>> readNode = snapshotAfterCommits.readNode(path1);
  Optional<NormalizedNode<?, ?>> readNode2 = snapshotAfterCommits.readNode(path2);
  ----
  First comes the creation of in-memory data tree instance. The schema context (containing the model mentioned above) of this tree is set. After that, two normalized nodes are built. The first one consists of a parent container, a child container and a parent ordered list which contains a key leaf and an ordinary leaf. The second normalized node is a child ordered list that also contains a key leaf and an ordinary leaf.

  == Overview
  YANG Tools is set of libraries and tooling providing support for use {rfc6020}[YANG] and {RFC7950}[YANG](YANG 1.1) for Java (or other JVM-based language) projects and applications.
  
  YANG Tools provides following features in OpenDaylight:
  
  - parsing of YANG sources and
  semantic inference of relationship across YANG models as defined in
  {rfc6020}[RFC6020] and {RFC7950}[RFC7950]
  - representation of YANG-modeled data in Java
  ** *Normalized Node* representation - DOM-like tree model, which uses conceptual
    meta-model more tailored to YANG and OpenDaylight use-cases than a standard XML
