问题+答案：
1、在SCHEMA中定义了requestype元素，但在xml中没有写上。应在<BasicCriteria>上之前加<requestType>元素内容。
2、问题出在：<xs:element name="BookDate">
        <xs:simpleType>
          <xs:restriction base="xs:string">
            <xs:pattern value="^\d{4}-\d{2}-\d{2}$">
            </xs:pattern>
          </xs:restriction>
        </xs:simpleType>
      </xs:element>
      <xs:element name="CheckInDate">
        <xs:simpleType>
          <xs:restriction base="xs:string">
            <xs:pattern value="^\d{4}-\d{2}-\d{2}$">
            </xs:pattern>
          </xs:restriction>
        </xs:simpleType>
      </xs:element>
按照你的SCHEMA的定义，BookDate和CheckInDate的内容应是"^2007-12-13$"的形式，但在XML中，你写的是“2007-12-13”形式。因而出错。


主要问题是这两个，改了后，在XMLSPY中可以通过。
另外，说一下个人看法：
  1、BookDate和CheckInDate的base用DATE类型会更合你的本意吧，为什么要用string类型呢？
  2、airportCode元素的定义有些重复。

<xs:element name="airportCode" maxOccurs="1">
          <xs:annotation>
            <xs:documentation>the IATA code</xs:documentation>
          </xs:annotation>
          <xs:complexType>
            <xs:sequence>
              <xs:element name="airportCode">
                <xs:annotation>
                  <xs:documentation>
                  </xs:documentation>
                </xs:annotation>
                <xs:simpleType>
                  <xs:restriction base="xs:string">
                    <xs:length value="3" />
                  </xs:restriction>
                </xs:simpleType>
              </xs:element>
            </xs:sequence>
          </xs:complexType>
        </xs:element>
在airportcode元素里再定义一个airportcode元素，我个人认为这没有必要。
<xs:element name="airportCode" maxOccurs="1">
   <xs:annotation>
      <xs:documentation>the IATA code</xs:documentation>
   </xs:annotation>
   <xs:simpleType>
      <xs:restriction base="xs:string">
          <xs:length value="3"/>
     </xs:restriction>
   </xs:simpleType>
</xs:element>
这是我改过的。

1.确实没有RequestType的内容,加上就好了
2.BookDate使用字符串而不是日期考虑到时区问题
3.IATA Code属于输入错误
