Exactly.

In the example provided, the template that receives the RTF as the
value of its $arg1 parameter is:

    <xsl:template match="str-split2words-func:*">
      <xsl:param name="arg1" select="/.."/>
      <xsl:param name="arg2"/>
......................Some nodes are copied here to the result tree
    </xsl:template>


It is instantiated in the (provided) stylesheet str-foldl.xsl in the
following way:

            <xsl:variable name="vFunResult">
              <xsl:apply-templates select="$pFunc[1]">
                <xsl:with-param name="arg0" 
                                select="$pFunc[position() > 1]"/>
                <xsl:with-param name="arg1" select="$pA0"/>
                <xsl:with-param name="arg2" 
                                select="substring($pStr,1,1)"/>
              </xsl:apply-templates>
            </xsl:variable>

            <xsl:call-template name="str-foldl">
		<xsl:with-param name="pFunc" select="$pFunc"/>
		<xsl:with-param name="pStr" 
                                select="substring($pStr,2)"/>
		<xsl:with-param name="pA0" select="$vFunResult"/>
            </xsl:call-template>

First a new temporary result is accumulated in $vFunResult. This is an
RTF, which has been produced by applying the first template above.

So in the xsl:call-template, the str-foldl template calls itself
recursively, passing this RTF as the value of the pA0 parameter, which
then is passed as the value of the $arg1 parameter, when the variable
$vFunResult is calculated again.

So, $arg1 contains an RTF.
