        <para>This data module contains MathML in order to produce the following:</para>

        </para>
        <para>Since MathML is not supported as of S1000D Issue 5.0, this would normally fail to validate. However, the -x option allows specified XML namespaces to be ignored when validating.</para>
        <para>To ignore MathML, for example:</para>
        <para>
          <verbatimText>$ s1kd-validate -x http://www.w3.org/1998/Math/MathML <data modules></verbatimText>
        </para>
