- org.opendaylight.yangtools.yang.data.util.DataSchemaContextTree

```
public final class DataSchemaContextTree
extends Object
```
Semantic tree binding a SchemaContext to a NormalizedNode tree. Since the layout of the schema and data has differences, the mapping is not trivial -- which is where this class comes in.
