It is not necessary to know the maximum length of the string to
produce.

Using FXSL template "iter" one simply writes the following:

<xsl:stylesheet version="1.0" 
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 xmlns:myAppendChar="f:myAppendChar" 
 exclude-result-prefixes="xsl myAppendChar">

 <xsl:import href="iter.xsl"/>
 
 <xsl:output omit-xml-declaration="yes"/>
  
  <myAppendChar:myAppendChar/>
  
  <xsl:template match="/">
  
   <xsl:variable name="vAppendChar" 
        select="document('')/*/myAppendChar:*[1]"/>
   
    <xsl:call-template name="iter">
      <xsl:with-param name="pTimes" select="1000"/>
      <xsl:with-param name="pFun" select="$vAppendChar"/>
      <xsl:with-param name="pX" select="''"/>
    </xsl:call-template>
  </xsl:template>
  
  <xsl:template match="myAppendChar:*">
    <xsl:param name="arg1"/>
    
    <xsl:value-of select="concat($arg1, '_')"/>
  </xsl:template>
    
</xsl:stylesheet>

As expected, in this case the result is a string of 1000 characters
"_'.


Hope that this really helped.
