Yow always can define parameters before calling a template. It is not very big price to pay. For example: <xsl:choose> <xsl:when test="$one"> <xsl:variable name="par_one" select="$one"/> </xsl:when> <xsl:when test="$done" > <xsl:variable name="par_one" select="$done"/> </xsl:when> </xsl:choose> ... <xsl:call-template name="base-function"> <xsl:with-param name="one" select="$par_one" /> </xsl:call-template> On Thursday, 11 Nov 1999, Clark C.
