We belive that XMLSpy is in error.  Its getting confused because
two different schemaLocaions are being used for the same namespace.

The XMLSpy developers, as I understand it, insist their intrepreation
of the spec is correct and that the instances are in error.

Last time I tried, Xerces validates documents like this.  Xerces
is the defalut validating parser for the oXygen XML editor, which
is much nicer than the last version of XMLSpy I used.
