  <xsd:annotation>
    <xsd:documentation>
      This pulls together examples 4-3, 4-4 and 4-5, illustrating include, chameleon include,
      and import, respectively.  Note that only the root element of the instance is prefixed,
      because all elements in all schema documents are declared locally and no
      elementFormDefault is specified.
