- * Returns schema of augmentation.
- *
- * <p>Returned schema is schema definition from which augmentation class was generated.
- * This schema is isolated from other augmentations. This means it contains
- * augmentation definition as was present in original YANG module.
- *
- * <p>Children of returned schema does not contain any additional augmentations,
- * which may be present in runtime for them, thus returned schema is unsuitable
- * for use for validation of data.
- *
- * <p>For retrieving {@link AugmentationSchemaNode}, which will contains
- * full model for child nodes, you should use method
- * {@link #getResolvedAugmentationSchema(DataNodeContainer, Class)}
- * which will return augmentation schema derived from supplied augmentation target
- * schema.
- *
- * @param augClass Augmentation class
- * @return Schema of augmentation or null if augmentaiton is not known in this context
- * @throws IllegalArgumentException If supplied class is not an augmentation
