-/**
- * Reference of statement source present in textual source format. Utility implementation
- * of {@link StatementSourceReference} for textual sources, this is preferred {@link StatementSourceReference}
- * for implementations of YANG / YIN statement stream sources.
- *
- * <p>
- * To create source reference use one of this static factories:
- * <ul>
- *   <li>{@link #atPosition(String, int, int)} - provides most specific reference of statement location, this is most
- *       preferred since it provides most context to debug YANG model.</li>
- *   <li>{@link #atPosition(int, int)}- provides location in text without knowing the name of the text file.</li>
- *   <li>{@link #inFile(String)}- provides a source name.</li>
- * </ul>
