与实体相似，复杂类型由标量属性或者其他复杂类型属性组成。
Like entities, complex types consist of scalar properties or other complex type properties.
业务对象是用于表示业务实体的主要机制，支持从具有标量属性的简单基本对象到大型复杂层次结构或对象图的任何实体。
Business objects are the primary mechanism for representing business entities, enabling everything from a simple basic object with scalar properties to a large complex hierarchy or graph of objects.
直到目前为止，修改对象属性时需要费一些特别的心思，例如使用左值子程序，你就可以直接操作子程序返回的标量。
Until now, special care had to be taken to allow modification of object attributes, for example. With lvalue subroutines, you can directly affect scalars returned by subroutines.
title属性是一个标量字符串。
XMLATTRIBUTES——创建元素属性的标量函数(必须总是用于xmlelement函数中)。
