Suppose I have a parameter passed to the style sheet called test, if test='yes' only then I need to create this first page with wordings "Hello World". Can I do that?

<xsl:if test="$test='yes'">
  <page-sequence master-reference="whatever-page-geometry-you-have-set-up">
    <flow flow-name="whatever-the-name-of-your-region-body-is">
      <block text-align="center">Hello World</block>
    </flow>
  </page-sequence>
</xsl:if>
