Are XML 2006 conference proceedings still available?

With the change from the XML conference to the XML-in-Practice
conference, the xmlconference.org domains for older conferences seem
to have gone away. Gone with them appear to be the proceedings of the
conferences that were hosted at those URLs. So XML 2001 papers are
still available at http://www.idealliance.org/papers/xml2001/, but XML
2006 papers at http://2006.xmlconference.org/ appear to be gone.

Does anyone know if there is a new home (now or planned) for these
conference proceedings? It would be a shame to lose this resource.

Thanks,
