$如图：
即：
| org.apache.fop.apps.FOPException: org.apache.fop.fo.ValidationException: "{http://www.w3.org/1999/XSL/Format}block" is not a valid child of "fo:root"! (See position 2653:25) |
【解决过程】
1.去看看对应的fo文件，
D:\tmp\tmp_dev_root\cgwin\home\CLi\develop\docbook\books\crifanlib_csharp\output\fo\crifanlib_csharp.fo
相关的内容为：
然后找到对应的xml源码，发现对应的preface.xml中的内容都是OK的。
2.后来找到原因了，原来是xml中，xi:include中的值，在原先的文件名后面，多写了个空格：
所以肯定是找不到对应的子xml文件了。
所以，解决办法很简单，把对应的多余空格去掉：
再重新编译，即可解决问题。
【总结】
此处用docbook编译生成pdf，出现：
| org.apache.fop.apps.FOPException: org.apache.fop.fo.ValidationException: "{http://www.w3.org/1999/XSL/Format}block" is not a valid child of "fo:root"! (See position 2653:25) |
的错误的：
原因是：
使用xi:include时给href赋值为xml文件名，结果后面多写了个空格
解决办法是：
去掉多余空格即可。
