      <xsd:documentation>
        An **PackageContainerType** is a tag used to provide logic.
        Child entries of an PackageContainerType tag only apply to
        machines that match the condition specified -- either
        membership in a group, or a matching client name.
        :xml:attribute:`PackageContainerType:negate` can be set to
        negate the sense of the match.
