可扩展标记语言XML在许多领域已经不可或缺，但是它的一个显著缺点是它的大小：标记一组数据会增加存储数据所需的空间、传输数据所需的带宽和解析数据所需的时间。我们提出了一种新的基于文档类型的压缩技术，表示为Relax NG模式。假设发送方和接收方事先就文件类型达成一致，符合要求的文件可以极其紧凑地传输。在具有高标记密度的几个数据集上，该技术比其他已知的xml感知压缩器（包括那些考虑文档类型的压缩器）压缩得更好。
The extensible markup language XML has become indispensable in many areas, but a significant disadvantage is its size: tagging a set of data increases the space needed to store it, the bandwidth needed to transmit it, and the time needed to parse it. We present a new compression technique based on the document type, expressed as a Relax NG schema. Assuming the sender and receiver agree in advance on the document type, conforming documents can be transmitted extremely compactly. On several data sets with high tag density this technique compresses better than other known XML-aware compressors, including those that consider the document type.
