我正在尝试定义我的第一个 xml 模式：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
    elementFormDefault="qualified"
    targetNamespace="http://www.example.net/test"
    xmlns:t="http://www.example.net/test">

    <xs:annotation>
        <xs:documentation>This schema describes the xml format that is used in for ILTIS stuff.</xs:documentation>
    </xs:annotation>
    <xs:complexType name="station">
        <xs:sequence>
            <xs:element name="transition" type="transition" minOccurs="1" />
        </xs:sequence>
    </xs:complexType>

    <xs:complexType name="transition">
        <xs:sequence>
            <xs:element name="wActions" type="wActions" maxOccurs="1" minOccurs="1"/>
            <xs:element name="oActions" type="oAction" maxOccurs="1" minOccurs="1"/>
        </xs:sequence>
        <xs:attribute name="from" type="xs:string" use="required"/>
        <xs:attribute name="to" type="xs:string" use="required"/>
    </xs:complexType>

    <xs:complexType name="wActions">
        <xs:sequence>
            <xs:element name="wMessage" type="wMessage" maxOccurs="2" minOccurs="1"/>
        </xs:sequence>
    </xs:complexType>

    <xs:complexType name="oActions">
        <xs:sequence>
            <xs:element name="trainRunMessage" type="trainRunMessage" maxOccurs="2" minOccurs="1"/>
            <xs:element name="wMessage" type="wMessage" maxOccurs="2" minOccurs="0"/>
        </xs:sequence>
    </xs:complexType>

    <xs:complexType name="trainRunMessage">
            <xs:attribute name="track" type="xs:string" use="required"/>
            <xs:attribute name="offset" type="xs:string" default="0"/>
            <xs:attribute name="station" type="xs:string" use="required"/>   
    </xs:complexType>


    <xs:complexType name="wMessage">
        <xs:attribute name="track" type="xs:string" use="required"/>
    </xs:complexType> 
</xs:schema>

但是我的氧气编辑器总是抛出这个错误信息：

src-resolve.4.1: Error resolving component 'transition'. It was detected that 'transition' has no namespace, but components with no target namespace are not referenceable from schema document 'file:/C:/Users/mbohlaender/Desktop/rules-example-schema2.xsd'. If 'transition' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'transition' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:/C:/Users/mbohlaender/Desktop/rules-example-schema2.xsd'.

我仍然不知道我做错了什么。请以简单的方式回答。

在<transition>元素的定义中，您引用了 type transition，这是 Oxygen 无法识别的。它不存在。您只定义了一个transition在您的架构中命名的复杂类型，因此该类型最终在http://www.example.net/test您使用t前缀导入的目标命名空间中。

尝试写作

<xs:element name="transition" type="t:transition" minOccurs="1" />
