| One question: the PyPointers link goes to
| 
| http://www.stud.ifi.uio.no/~lmariusg/download/python/xml/xptr.html
| 
| Which gives 404.  Lars, is this still something you stillwant
| listed?  If so, where do I point to?

Just remove it.  That module implements a now obsolete XPointer
syntax that is totally different from the current XPath-based one, and
so really is useless.
