Sorry, meant to send to the group:

BTW, here are three generated valid instance documents, as validated
against the XSD:

This is perfectly valid XML according to the XSDs since they leave the
typing of a cimReference wide open and is more inline with how I would
*like* to use the instance XML, referring back to a unique
ComputerSystem, and unique OperatingSystem.  I just don't see exactly
how I would do this.
