Re: Wish List: Allow <xsl:choose> within <xsl:call-template>

Well, if you really - really want to use
logic right in the place where you are calling templates,
you can
   <xsl:call-template name="base-function">
       <xsl:with-param name="one">
          <xsl:when test="$one">
             <xsl:copy-of select="$one"/>
          </xsl:when>
          <xsl:when test="$done" >
             <xsl:copy-of select="$done" />
          </xsl:when>
       </xsl:with-param>
   </xsl:call-template>

This will save you from creating extra 10 variables.
Inside xsl:template body you can use 
 select ="string($one)"

It does not help in the situation when you only
want to send sub-set of parameters.
Although it is a nice feature to have,
I am not sure that it is something unavoidable.
The worth comes to worth you can send 
some special value (like "to-be-replaced-with-default")
that internally will be substituted with default.
