The container element, as just mentioned, is the logicalparent of the topic element.
正如刚才所述，container 元素是 topic 元素的逻辑父元素。

Note that the logicalparent of an element can potentially change depending on your application's functionality, and keeping the value of this property will not reflect that change.
请注意，项目的逻辑父项目有可能视应用程式的功能而变更，且保留这个属性的值并不会反映该变更。

This significantly speeds the merge session, because only those fragments that are changed are loaded (along with their parent containers of the logical model).
