xsd 分解出多用途属性 [英] xsd factor out multiple use attribute

问题描述

我不知道如何分解这段 XSD:

I'm not sure how to factor out this piece of XSD:

<xs:attribute name="status" use="required">
    <xs:simpleType>
        <xs:restriction base="xs:token">
            <xs:enumeration value="not run"/>
            <xs:enumeration value="passed"/>
            <xs:enumeration value="failed"/>
        </xs:restriction>
    </xs:simpleType>
</xs:attribute>

在 和 标签中都需要:

which is needed in both <test> and <step> tags:

<?xml version="1.0" encoding="UTF-16"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="FlowBi:Emis:FeatureTests"

elementFormDefault="qualified" 
attributeFormDefault="unqualified">
<xs:element name="featureTests">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="test" minOccurs="1" maxOccurs="unbounded">
                <xs:complexType>
                    <xs:sequence> 
                        <xs:element name="summary" type="xs:string"/>
                        <xs:sequence>
                            <xs:element name="step" minOccurs="0" maxOccurs="unbounded">
                                <xs:complexType>
                                    <xs:simpleContent>
                                        <xs:extension base="xs:string">
                                            <xs:attribute name="status" use="required">
                                                <xs:simpleType>
                                                    <xs:restriction base="xs:token">
                                                        <xs:enumeration value="not run"/>
                                                        <xs:enumeration value="passed"/>
                                                        <xs:enumeration value="failed"/>
                                                    </xs:restriction>
                                                </xs:simpleType>
                                            </xs:attribute>
                                        </xs:extension>
                                    </xs:simpleContent>
                                </xs:complexType>
                            </xs:element>
                        </xs:sequence>
                    </xs:sequence>
                    <xs:attribute name="status" use="required">
                        <xs:simpleType>
                            <xs:restriction base="xs:token">
                                <xs:enumeration value="not run"/>
                                <xs:enumeration value="passed"/>
                                <xs:enumeration value="failed"/>
                            </xs:restriction>
                        </xs:simpleType>
                    </xs:attribute>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:element>
</xs:schema>

最好将重复的部分分解出来并在每个使用它的地方引用它，但我不确定如何对属性类型执行此操作.

It would be nice to factor out the repeated section and just reference it in each place it is used but I'm not sure how to do this for attribute types.

推荐答案

应该这样做
