  Hum, I would check for basic well-formedness here because it just
too easy to break the XML file while editing with a text editor
if the call fails to build a parsed document suggest to reedit from
scratch, based on the current buffer or just abort the edit.

  Numerous newbies will get trapped in vi, get lost and looking for
a safe exit path :-)
