当使用castor，而我们又懒得不想写castor的map文件，恰恰这时候javabean里还持有一个list，这个时候会生成什么样的xml？当使用castor，而我们又懒得不想写castor的map文件，恰恰这时候javabean里还持有一个list，这个时候会生成什么样的xml？

  <?xml version="1.0" encoding="UTF-8" ?> 
- <routebean>
- <flights xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:java="http://java.sun.com" number="426" xsi:type="java:castortest.FlightBean">
  <arrival-time>8:42a1</arrival-time> 
  <departure-time>6:23a1</departure-time> 
  <carrier>AR1</carrier> 
  </flights>
- <flights xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:java="http://java.sun.com" number="426" xsi:type="java:castortest.FlightBean">
  <arrival-time>8:42a2</arrival-time>

  <carrier>AR2</carrier> 
  </flights>
  <to>to</to> 
  <from>from</from>

生成这样的xml，flex是否可以解析？
