Re: [xml] string-range in xpointers from python?

O.k, so this is better, some:

      Geometric representation of signals can provide a compact
      characterization of signals and can simplify analysis of their
      performance as modulation signals.

Unable to convert XPath object type 7

I see this same error from a list posting a year ago, May. I'm using
libxml2 2.6.26. Is there more complete support in CVS? Should I be
getting my devel setup functional, and see about providing a patch or
two?
