将已经损坏的对以前键值的引用移除。
注意，按键值相关的表可以嵌套，如清单5中所示，或者由嵌入在文档中的链接引用为相关表名称上的属性。
Note that tables related by key can be nested, as in Listing 5, or referenced by a link embedded within the document as attributes on the related table name.
下面的示例说明了如何在使用和不使用新方法的情况下向标识符包添加一个用键值标识的引用。
The following examples illustrate adding a keyed reference to an identifier bag with and without using the new methods.
首先要创建一个用键值标识的引用来描述要建立的关系。
A keyed reference is created which describes the relationship to be formed.
为此，您可以使用Ruby中的hash类，它允许您创建键值对(类似于数组)，但是随后可以轻松地通过键引用它们。
For this purpose, you use the hash class in Ruby, which allows you to create key-value pairs (in what appears to be an array), but then easily reference them later by key.
另一种是在 plugin.properties文件中定义键值对并在Text字段中引用键。
产生的集合可以包含一个如下所述的成员：该成员引用由第二个集合中的元素组成的集合，这些元素与第一个集合中的键值相匹配。
The resulting collection can contain a member that references a collection of elements from the second collection that match the key value from the first collection.
