The relevant official namespaces for the W3C XML Schema REC as
published are http://www.w3.org/2001/XMLSchema and
http://www.w3.org/2001/XMLSchema-instance.  If you don't use those
exact namespaces (in schema docs and instance docs respectively) you
don't get the XML Schema semantics.  There are few if any parsers
still left which implement the preliminary 1999 version.
