  Well I started working on it, hoping it would be simple and quick.
Unfortunately, I started to get informations about published drafts being
different from an unavailable ISO standard, various requests to get test
suites left and right were left unanswered, I lost interest, and it
seems nobody uses it or try to use libxml2 version.
  So far it has been very disapointing in spite of high initial expectations,
growing a test suite would certainely help, not sure each and every case
should be bugzilla'ed, and I'm still unclear how mush interrest there really
is for it. I don't know what's the best approach, and I don't have that much
time right now (though a slow but reliable implementation should not be too
hard based on the existing code).
