[xsl] Params being intialised with variables based on attributes

["gary cor" <stuff4gary at hotmail dot com>]

Hi,

I have many when test's to reference global variables in my code
and I can't seem to find a way of optimising the code so I am
wondering if someone can help.

For instance have some parameters in templates that are initialised with big 
statements like follows-


<xsl:template match=mediaobject ...
<xsl:param name="column-number">
   <xsl:choose>
       <xsl:when test="@grouping='avgroup'">
           <!-- This is a global variable -->
           <xsl:value-of select="$avgroup-column-number"/>
       </xsl:when>
       <xsl:when test="@grouping='gallery'">
           <xsl:value-of select="$gallery-column-number"/>
       </xsl:when>
       <xsl:when test="@grouping='free'">
           <xsl:value-of select="$free-column-number"/>
       </xsl:when>
       <xsl:when test="@grouping='inline'">
           <xsl:value-of select="$inline-column-number"/>
       </xsl:when>
       <xsl:when test="@grouping='list'">
           <xsl:value-of select="$list-column-number"/>
       </xsl:when>
       <xsl:when test="@grouping='person'">
           <xsl:value-of select="$person-column-number"/>
       </xsl:when>
       <xsl:when test="@grouping='wallpaper'">
           <xsl:value-of select="$wallpaper-column-number"/>
       </xsl:when>
       <xsl:otherwise>
           <xsl:value-of select="$mediaobject-column-number"/>
       </xsl:otherwise>
   </xsl:choose>
</xsl:param>

I suppose I sort of want to do something like...

<xsl:value-of select="${@grouping}-column-number"/>

but I know this isn't legal XSLT

Any ideas?

Cheers G.
