Example
Here's a brief example that uses the true() function:
    <?xml version="1.0"?>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

      <xsl:output method="text"/>

      <xsl:variable name="newline">
    <xsl:text>
    </xsl:text>
      </xsl:variable>

      <xsl:template match="/">
        <xsl:value-of select="$newline"/>
        <xsl:text>A test of the true() function:</xsl:text>

        <xsl:value-of select="$newline"/>
        <xsl:value-of select="$newline"/>
        <xsl:choose>
          <xsl:when test="true()">
            <xsl:text>   "true()"   returned true!</xsl:text>
          </xsl:when>
          <xsl:otherwise>
            <xsl:text>   "true()"   returned false!</xsl:text>
          </xsl:otherwise>
        </xsl:choose>
      </xsl:template>
    </xsl:stylesheet>
When using this stylesheet against any XML document, it generates this less-than-exciting result:
    A test of the true() function:

       "true()"   returned true!
