十三、在类型中添加属性

                                            <xs:attribute name="id" use="required" type="xs:ID"></                              xs:attribute>

                                          <xs:attribute name="name" default="aaa"></xs:attribute>

                     </xs:attributeGroup>

   解析：use=”required” 代表必填项

                Type=”xs:ID” 代表主键 xml中主键必须以字母或_下划线开头

                Default 代表默认值

十四、将属性添加到组中

         定义：

                   <xs:attributeGroup name="stugroup">

                                   <xs:attribute name="id" use="required" type="xs:ID"></                              xs:attribute>

                                          <xs:attribute name="name" default="aaa"></xs:attribute>

                     </xs:attributeGroup>

       引用：

                   <xs:attributeGroup name="stugroup">

                                   <xs:attribute name="id" use="required" type="xs:ID"></                              xs:attribute>

                                          <xs:attribute name="name" default="aaa"></xs:attribute>

                     </xs:attributeGroup>
