If element substitution is imperative to your design or you need to make elements transparent to other schemas, use the Salami slice style or Garden of Eden.
如果元素替代对于您的设计很重要，或者您需要让元素对其他模式是透明的，那么请使用Salamislice风格或Gardenof Eden。
For example, there are multiple ways to describe values from a set that may vary: xs: choice, element substitution groups, abstract elements, abstract types, and many more.

They then traverse a substitution chain of element declarations or a type hierarchy to determine whether the element declaration satisfies the substitution or type derivation requirements.
然后遍历元素声明的代替链或类型层次结构，以决定元素声明是否满足代替或类型衍生要求。
Perhaps the easiest way to extend NIEM is through the use of substitution groups, which allow you to declare your own element and specify that it is substitutable for a NIEM element.
也许扩展NIEM最容易的方式是通过使用置换组来做到，置换组允许您声明自己的元素和指定它是NIEM元素的替代。

By declaring an element or type to be abstract, XML Schema provides a mechanism to force substitution for it.
通过声明抽象的元素或者类型，XMLSchema提供了一种强制替换机制。
Both functions require that the provided schema documents declare or define the instance element to be tested and the substitution group head element or the referenced type.
两个函数都要求提供的模式文档声明或定义要测试的实例元素，以及代替组head元素或引用类型。
The character is replaced by a substitution character before parsing takes place, and results in the element tag name throwing a SQL error code "16110 XML Syntax error.

If the XPath expression on the test attribute has evaluated to true, then the specified type is selected as a substitution for the one declared on the element.
如果test属性上的XPath表达式最终值为true，那么将选择指定的type替换元素中声明的类型。
It returns true if the element in the instance document is declared to be in the substitution group headed by the element identified by the element QName.
如果实例文档中的元素被声明为位于以元素QName指定的元素为首的代替组中，则返回true。
Schema-element (Person) matches an element node which is declared to be in the substitution group headed by the Person element.
schema -element (Person)匹配一个元素节点，该节点必须在以Person开头的代替组中声明。
Of course, the block of element declarations that are substitution group members can be managed in a schema module that is stored separately and included in a main schema.
当然，作为替换群成员的元素声明块可以在一个单独存储并包含在一个主模式中的模式模块中管理。
