  This is dangerous. The reason of the URI base fixup is to garantee that
URI references done from the XInclud'ed documents stay valid after the
inclusion. If you don't do the fixup you basically break URI References
done from within the document:
  http://www.w3.org/TR/xinclude/#base

  It can be disabled in XInclude at user option, libxml2 implements this.

  You would have to define what --nofixup-base-uris actually does,
it's unclear. At least it doesn't seems defined in a standard way.
