[xsl] dynamic template invocation

[ac <ac@xxxxxxxxxxxxx>]

Hi,

Is there, or shouldn't there be, a way to invoke templates dynamically 
as in:

<xsl:apply-templates mode="$mode"/> or
<xsl:call-template name="$name"/>

rather than :
<xsl:choose>
   <xsl:when test="$mode eq 'mode1'"><xsl:apply-templates mode="mode1"/>
   <xsl:when test="$mode eq 'mode2'"><xsl:apply-templates mode="mode2"/>
   <xsl:when test="$mode eq 'mode3'"><xsl:apply-templates mode="mode3"/>
   ...
</xsl:choose>
or
<xsl:choose>
   <xsl:when test="$mode eq 'mode1'"><xsl:call-template name="name1"/>
   <xsl:when test="$mode eq 'mode2'"><xsl:call-template name="name2"/>
   <xsl:when test="$mode eq 'mode3'"><xsl:call-template name="name3"/>
   ...
</xsl:choose>

as the <xsl:choose/> seems clumsy, verbose, repetitive, error-prone, and 
counter productive,
especially when also passing invocation parameters (<xsl:with-param .../>) ?

A sample use case may be letting a user select in which mode she wishes 
to run a process, payroll for example, in trial, debug, report, post, 
archive, or purge modes.

Thanks,
ac
