这就是我在XSD中看到的。角色只是简单的
xs:string，主要用于文档。
<xs:element name="roles" minOccurs="0"> <xs:annotation> <xs:documentation source="version">3.0.0+</xs:documentation> <xs:documentation source="description"> The roles the contributor plays in the project. Each role is described by a <pre>role</pre> element, the body of which is a role name. This can also be used to describe the contribution. </xs:documentation> </xs:annotation> <xs:complexType> <xs:sequence> <xs:element name="role" minOccurs="0" maxOccurs="unbounded" type="xs:string"/> </xs:sequence> </xs:complexType></xs:element>
