java中提供了xjc.exe可以將xds轉(zhuǎn)成類方法，但是用命令行導(dǎo)CDA.xds是報(bào)如下錯(cuò)誤：

原來是ID和id在Java中沖突所致，參考了一篇技術(shù)文檔搞定。
1）在源POCD_MT000040.xsd文件中
ID" type="xs:ID">
替換成：
ID" type="xs:ID">
ID1">
2）在源POCD_MT000040.xsd頭中添加
xmlns:mif="urn:hl7-org:v3/mif"
xmlns="urn:hl7-org:v3"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
elementFormDefault="qualified"
jaxb:version="1.0"
jaxb:extensionBindingPrefixes="xjc">
3）最后執(zhí)行命令行 xjc -extension CDA.xsd 搞定
-extension???????? :? allow vendor extensions - do not strictly follow the
Compatibility Rules and App E.2 from the JAXB Spec
