在我的XSD中,我希望能够指定元素的顺序并不重要.这是我有的：
<xs:element name="ADT_A08_231_GLO_DEF">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="1" maxOccurs="1" name="EVN_EventTypeSegment" type="xs:string" />
<xs:element minOccurs="1" maxOccurs="1" name="PID_PatientIdentificationSegment" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="1" name="PD1_PatientAdditionalDemographicSegment" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
如何使EVN和PID元素在XML文件中随机(先是EVN,然后是PID或第一个PID元素,然后是EVN元素)？
<EVN_EventTypeSegment>Test</EVN_EventTypeSegment> <PID_PatientIdentificationSegment>PIDTest</PID_PatientIdentificationSegment>
要么：
<PID_PatientIdentificationSegment>PIDTest</PID_PatientIdentificationSegment> <EVN_EventTypeSegment>Test</EVN_EventTypeSegment>
使用xs：all而不是xs：sequence.
