<xsl:template name="ApplyTemplatesOrCreate"> 
    <xsl:param name="elemName" select="''" /> 
    <xsl:param name="elemDefault" select="''" /> 

    <xsl:variable name="elem" select="*[name() = $elemName]" /> 

    <xsl:choose> 
    <xsl:when test="$elem"> 
     <xsl:apply-templates select="$elem" /> 
    </xsl:when> 
    <xsl:otherwise> 
     <xsl:if test="$elemName != ''"> 
     <xsl:element name="{$elemName}"> 
      <xsl:value-of select="$elemDefault" /> 
     </xsl:element> 
     </xsl:if> 
    </xsl:otherwise> 
    </xsl:choose> 
</xsl:template> 

appel comme:

<xsl:call-template name="ApplyTemplatesOrCreate"> 
    <xsl:with-param name="elemName" select="'SalMin'" /> 
    <xsl:with-param name="elemDefault" select="'1000'" /> 
</xsl:call-template>
