 * <h2>When to Use DomUtils</h2>
 * <p>Use DomUtils methods when you need:
 * <ul>
 * <li>Maven-specific element ordering (insertNewElement, insertContentElement)</li>
 * <li>High-level helpers (addGAVElements, createDependency, createPlugin)</li>
 * <li>Null-safe operations (updateElementContent, removeElement)</li>
 * <li>Update-or-create patterns (updateOrCreateChildElement)</li>
 * </ul>
