当我尝试解析Aramex 运输服务 WSDL（创建货件所需的）时，出现命名空间错误，并显示以下错误日志：
C:\Program Files\Java\jdk1.6.0_37\bin>wsimport.exe -keep -verbose D:\ATG\aramex\shipping-services-api-wsdl\shipping-services-api-wsdl.wsdl -d D:\ATG\aramex\java\
parsing WSDL...
[WARNING] src-resolve.4.2: Error resolving component 'ser:guid'. It was detected that 'ser:guid' is in namespace 'http://schemas.microsoft.com/2003/10/Serialization/', but components from this namespace are not referenceable from schema document 'file:/D:/ATG/aramex/shipping-services-api-wsdl/shipping-services-api-wsdl.wsdl#types?schema1'. If this is the incorrect namespace, perhaps the prefix of 'ser:guid'
needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:/D:/ATG/aramex/shipping-services-api-wsdl/shipping-services-api-wsdl.wsdl#types?schema1'.

我怎样才能摆脱错误？
