  <title>Adding parameters to existing XSLT steps</title>
  <shortdesc>You can pass parameters from the Ant build to existing XSLT steps in both the pre-processing pipeline and
    certain DITA-OT transformations. This can be useful if you want to make the parameters available as global
      <xmlelement>xsl:param</xmlelement> values within XSLT overrides.</shortdesc>

      <p>The following plug-in passes the parameters defined in the <filepath>insertParameters.xml</filepath> file as

        something new with the generated content.</p>
