But you can probably work around the issue by using <xsl:choose> clauses.

<xsl:choose>
 <xsl:when test="$mode='blah'">
  <xsl:apply-templates select='category-list' mode='blah'/>
 </xsl:when>
 <xsl:when test="$mode='foo'">
  <xsl:apply-templates select='category-list' mode='foo'/>
 </xsl:when>
</xsl:choose>
