1·Labeling scheme is the basis for Extensible Markup Language (XML) query processing. The traditional labeling schemes use Numbers based on natural order, which is hard to support XML updating.

编码技术是可扩展标记语言(XML)查询处理的基础，传统编码技术利用自然数进行编码，很难支持XML动态更新。

2·This paper introduces in detail the generalized labeling algorithm, programming consideration and implementation scheme, and discusses the applicable scale of the algorithm.

详细介绍了广义标号算法、程序设计思想及其实现方案，并讨论了算法的适用规模。
