Something along the following lines should work for you: <xsl:choose> <xsl:when test="$color='red'"> <xsl:call-template name="text-template> <xsl:param name="tint" expr="'pink'"> <xsl:param name="shade" expr="'maroon'"> </xsl:call-template> </xsl:when> <xsl:when test="$color='violet"> <xsl:call-template name="text-template> <xsl:param name="tint" expr="'lavender'"> <xsl:param name="shade" expr="'indigo'"> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:call-template name="text-template/> </xsl:otherwise> </xsl:choose> <xsl:template name="text-template"> <xsl:variable name="color" expr="Get/Color/From/Some/@Attribute"> <xsl:param-variable name="tint" expr="'light gray'"> <xsl:param-variable name="shade" expr="'dark gray'"> <xsl:text> The color is <xsl:value-of select="$color"/>... The tint is <xsl:value-of select="$tint"/> (not there, is it?)... The shade is <xsl:value-of select="$shade"/> (not there either!) </xsl:text> </xsl:template> Note the use of defaults (I copied the ones from the otherwise clause). I hope this helps. ..............
