Can I have one XML Schema (XSD) include another XML-Schema?
提问by Robert Gould
I currently have two XSD schemes and one is a "light" version of the other. Right now I have everything in the "light" version repeated in the "complete" schema, but this becomes a pain when I need to make a change, and it goes against the DRY principle anyways, so I was wondering if there was an element that served to include another schema into a schema, so I can have my "complete" inherit from the "light" schema to reduce maintenance hurdles.
我目前有两个 XSD 方案，一个是另一个的“轻型”版本。现在我在“完整”模式中重复了“轻”版本中的所有内容，但是当我需要进行更改时这变得很痛苦，并且无论如何它都违反了 DRY 原则，所以我想知道是否有一个元素它用于将另一个模式包含到模式中，因此我可以从“轻量级”模式继承“完整”模式以减少维护障碍。

There are two methods for this.
有两种方法可以做到这一点。
<xsd:include schemaLocation="pathToFile" />should be used for including files of the same namespace.
<xsd:include schemaLocation="pathToFile" />应该用于包含相同命名空间的文件。
<xsd:import namespace="namespace" schemaLocation="pathToFile" />should be used for include files in a different namespace. Usually you will specify the namespace given as the targetNamespace of the imported schema.
<xsd:import namespace="namespace" schemaLocation="pathToFile" />应该用于包含不同命名空间中的文件。通常，您将指定给定的命名空间作为导入模式的 targetNamespace。
