I suppose you are facing this old Xerces bug:
https://issues.apache.org/jira/browse/XERCESJ-1102

You can either:
1. patch it for yourself or
2. generate outputs in two steps:

   a. use xmllint for resolving XIncludes into a single XML file (xmllint
handles xml:base correctly)
   b. generate outputs using this single file


More info about xmllint can be found at http://xmlsoft.org/xmllint.html
It can be downloaded from http://xmlsoft.org/downloads.html

For DocBook v5.0+ you can call it this way:
xmllint --xinclude -o resolved.xml original.xml
