Re: [xsl] Is it possible to set the mode dynamically?

["Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Another way would be to associate a function with each mode:

<xsl:function name="f:apply-pivot-table">
  <xsl:param name="select"/>
  <xsl:apply-templates select="$select" mode="pivot-table"/>
</xsl:function>

<xsl:function name="f:apply-default">
  <xsl:param name="select"/>
  <xsl:apply-templates select="$select" mode="#unnamed"/>
</xsl:function>

<xsl:variable name="apply" select="if ($table-name = 'pivot-table-payload')
then f:apply-pivot-table#1 else f:apply-default#1"/>

and then replace the <xsl:apply-templates select="X"/> instruction with
<xsl:sequence select="$apply(X)"/>

(But having introduced higher order functions, you might then find you can do
everything with higher order functions and don't need template rule matching
at all).

the only alternative would be to use a choose and then hardcode the mode -
which works, but just wondering if there was a cleaner way?
