1·Using macros like this significantly reduces typing because you do not have to constantly be writing and rewriting variable bindings, derivations, and parameter passing.
使用这样的宏可以显著减少代码输入量,因为不必不断地编写和重新编写变量绑定、派生和参数传递。
2·In XML schemas you can use abstract classes or just tags specifying extensions or derivations of base types.
在XML模式中,可以使用抽象类或仅使用指定基类型扩展或派生的标记来做到这一点。
3·Service description entities are a category of metadata in the information model maintained by Service Registry that includes physical documents, logical derivations and generic objects.
服务描述实体是Service Registry提供的信息模型中的一个元数据类别,其中包括物理文档、逻辑派生和一般对象。
4·Examples: definition of source and target systems, their table and fields structures and attributes, documentation for auditing derivations and dependencies.
示例:源和目标系统的定义、表和字段的结构和属性、用于审计派生和依赖关系的文档。
5·The rule allow some obviously invalid derivations (that is, restriction allows more than base).
规则允许一些明显无效的派生元素(也就是说,限制类型允许比基础类型更多的元素)。
