      This provides an example of validating an instance with multiple namespaces.
      chapter03env.xsd imports chapter03ord.xsd, which imports chapter03prod.xsd, which
      imports chapter03prod2.xsd.  The "form" attribute is used to indicate whether
      element-type and/or attribute names should be qualified in the instance.
