将原始二进制数据与XML一起存储的最标准Java方法是什么？

import javax.xml.parsers.DocumentBuilderFactory;

            // 创建XML文档
            DocumentBuilderFactory documentFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder documentBuilder = documentFactory.newDocumentBuilder();
            Document document = documentBuilder.newDocument();

            // 创建根元素
            Element rootElement = document.createElement("data");
            document.appendChild(rootElement);

            // 创建二进制数据
            byte[] binaryData = new byte[]{72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100};

            // 将二进制数据转换为Base64编码的字符串
            String base64Data = Base64.getEncoder().encodeToString(binaryData);

            // 将Base64编码的字符串嵌入到XML文档中
            Element binaryElement = document.createElement("binaryData");
            binaryElement.appendChild(document.createTextNode(base64Data));
            rootElement.appendChild(binaryElement);

            TransformerFactory transformerFactory = TransformerFactory.newInstance();

            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            DOMSource source = new DOMSource(document);
            StreamResult result = new StreamResult(System.out);
            transformer.transform(source, result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
