-This attempts to conform to the DOM3 implementation in Xerces. It tries to
-conform to DOM3 as of Xerces 2.6.0. I'm not one to stay on the bleeding edge
-but it is as close to a standard interface for load & save as you can get
-and I didn't want to work around the fact that current serializers aren't
-very good.
