Question

我有三个XSD：deviceprofile.xsd，relatedType.xsd和profilelist.xsd

deviceprofile.xsd是引用relatedtype.xsd的根XSD，后者又指profilelist.xsd。

relatedtype.xsd和profilelist.xsd之间的引用工作正常，但deviceprofile.xsd和relatedType.xsd之间的关系给出了问题。

我已经使用相关的命名空间导入了XSD，但在使用JAXB解析deviceprofile.xsd时，它给出了：

[ERROR] src-resolve: Cannot resolve the name 'relatedData' to a(n) 'element decl
aration' component.
line 47 of file:/D:/Personal/Java/Trials/src/com/asl/trials/cea/xml/deviceprof
ile.xsd

Failed to parse a schema.

XSD都在同一个目录中，所以我可以肯定它不是路径问题。

有人可以指出我做错了吗？

我已附上以下XSD的相关摘要（以防万一）：

deviceprofile.xsd

在deviceprofile.xsd架构中，您需要声明urn:schemas-ce-org:ce-html-server-caps-1-0命名空间，然后在ref值中包含相应的前缀。下面我使用了foo前缀：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns="urn:schemas-upnp-org:remoteui:uilist-1-0"
    targetNamespace="urn:schemas-upnp-org:remoteui:uilist-1-0" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:foo="urn:schemas-ce-org:ce-html-server-caps-1-0"
    elementFormDefault="qualified" 
    attributeFormDefault="unqualified" id="uilist">
    <xs:import namespace="urn:schemas-ce-org:ce-html-server-caps-1-0"
        schemaLocation="relatedtype.xsd" />
    <xs:element name="uilist">
        <xs:complexType>
            <xs:sequence>
                <xs:element ref="foo:relatedData" minOccurs="1" maxOccurs="1" />
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>
