XML：如何创建有效的namespace + xsd架构

I've got a problem with configuring XML + XSD. I wanted to use a namespace in my XML, but I don't know how to write a XSD for this.

我在配置XML + XSD时遇到了问题。我想在我的XML中使用命名空间,但我不知道如何为此编写XSD。

The 'a' namespace stands for 'actor'. I know it isn't good idea to do something like that, but it's just a excercise :)

'a'命名空间代表'actor'。我知道做这样的事情不是一个好主意,但它只是一个练习:)

If I would use something like

如果我会使用类似的东西

<role name="xxx">
    <actorName>asd</actorName>
    ...
</role>

etc. it will be valid, but I really wanted to learn how to use namespaces.

它将是有效的,但我真的想学习如何使用命名空间。

This is my XML file:

这是我的XML文件:
