Niel, I just posted this question, and only then found this tread. Here it is again:
OK, it turns out Apple's official stand is that Bootcamp 5 does not support Win XP. However, a quick web search reveals that many users have indeed installed Win XP on OSX 10.8 machines without Parrallels or Fusion, etc. If this is so, how is it done? Are users installing an earlier version of Bootcamp?
All of this really is covered at http://www.apple.com/support/bootcamp
