大多数的映射转换操作针对的是常规标量数据，因此数组需要一个特殊的转换。
Most mapping transforms operate on regular scalar data and so arrays require a special transform.
图3展示了如何在示例数据上执行标量规则。
Figure 3 shows how a scalar rule is executed on sample data.
因为这都是些标量函数，所以将为结果集的每一行创建XML数据类型的结果。
Since these are scalars functions, for each line of the result set, a result of the XML data type is created.
