<xsd:element name="criteria">
    <xsd:annotation>
        <xsd:documentation>Each definition is described by a number of tests, referenced by the individual criterion elements.  The criteria element is the high level container for all the tests and represents the meat of the definition.  These tests are broken up into two different categories, software and configuration.  This categorization allows users to differentiate between the 'software on disk' portion of a definition and the 'how is the machine configured' portion of the definition.</xsd:documentation>
