抽象类模型中的XML
您只能使用简单的抽象类模型对XML模式进行建模。例如，这使架构师可以在更高的抽象层次上开始工作而无需担心Schema的实现细节。虽然随后可以使用工具箱的“ XML Schema”页面完善这种抽象模型，但也可以直接由Enterprise Architect的Schema Generator生成该抽象模型，在这种情况下，Schema Generator应用一组默认映射来转换XSD文件的抽象模型。

这是早期Employee Details示例模型的简单Class元素版本。它不使用特定于XSD的构造型或标记值。 |

可以从示例模型生成此架构片段： <？xml version =“ 1.0”？> <xs：schema xmlns：xs =“ http://www.w3.org/2001/XMLSchema”> <xs：simpleType name =“ Status”> <xs：restriction base =“ xs：string”> <xs：enumeration value =“全职” /> <xs：enumeration value =“ Part-Time” /> <xs：enumeration value =“ Casual” /> <xs：enumeration value =“ Contract” /> </ xs：restriction> </ xs：simpleType> <xs：element name =“ Person” type =“ Person” /> <xs：complexType name =“ Person”> <xs：sequence> <xs：element name =“ firstName” type =“ xs：string” /> <xs：element name =“ surName” type =“ xs：string” /> <xs：element name =“ birthDate” type =“ xs：string” /> <xs：element name =“ gender” type =“ xs：string” /> <xs：element name =“ contactDetails” type =“ ContactInfo” /> </ xs：sequence> </ xs：complexType> <xs：element name =“ Employee” type =“ Employee” /> <xs：complexType name =“ Employee”> <xs：complexContent> <xs：extension base =“ Person”> <xs：sequence> <xs：element name =“ status” type =“ Status” /> <xs：element name =“ jobTitle” type =“ xs：string” /> <xs：element name =“ startDate” type =“ xs：date” /> <xs：element name =“ department” type =“ xs：string” /> </ xs：sequence> </ xs：extension> </ xs：complexContent> </ xs：complexType> <xs：element name =“ EmployeeRecords” type =“ EmployeeRecords” /> <xs：complexType name =“ EmployeeRecords”> <xs：sequence> <xs：element name =“ Employee” type =“ Employee” minOccurs =“ 0” maxOccurs =“ unbounded” /> </ xs：sequence> </ xs：complexType> <xs：element name =“ ContactInfo” type =“ ContactInfo” /> <xs：complexType name =“ ContactInfo”> <xs：sequence> <xs：element name =“ homePhone” type =“ xs：string” /> <xs：element name =“ mobilePhone” type =“ xs：string” /> <xs：element name =“ officePhone” type =“ xs：string” /> <xs：element name =“ email” type =“ xs：string” /> <xs：element name =“ streetAddress” type =“ xs：string” /> </ xs：sequence> </ xs：complexType> </ xs：schema> |
