Default Using Parameter to call another template

I'm trying to use a param to be the name of the next template I call:

For instance, this code works fine:

<xsl:template name="preprinted-form">
<fo:block>
<fo:table table-layout="fixed" space-before.optimum="0pt" space-after.optimum="0pt">
<xsl:call-template name="sales-order-columns"/>
     ....

I want to be able to do this:
<xsl:template name="preprinted-form">
<xsl:param name="column_prg"/>
<fo:block>
<fo:table table-layout="fixed" space-before.optimum="0pt" space-after.optimum="0pt">
    <xsl:call-template name="$column_prg"/>
     .....

So I can make the call:
<xsl:call-template name="preprinted-form">
<xsl:with-param name="column_prg" select="sales-order-columns"/>
</xsl:call-template>

Is this possible? Or anything like it?
Currently, this gives and error:
XTSE0280: Invalid QName {$column_prg}


Here is what sales-order-columns contains:
<xsl:template name="sales-order-columns">
        <fo:table-column column-width="0.8in" />
        <fo:table-column column-width="0.45in" />
        <fo:table-column column-width="1.35in" />
        <fo:table-column column-width="3.35in" />
        <fo:table-column column-width="0.70in" />
        <fo:table-column column-width="0.45in" />
        <fo:table-column column-width="0.80in" />
    </xsl:template>

The idea of this is because I am overlaying tables on top of one another. I want to be able to create this template so that it can be used on many business forms.

I am using saxon8.jar with jre1.5.0_06.

Nice idea but it doesn't work. The template name in call-template must be supplied literally as a QName.

If you want a dynamic call it can usually be achieved using apply-templates. Take a look at Dimitre Novatchev's FXSL library for an extreme example of what can be achieved without departing from the XSLT standard.
