How can i customize some elements?

Hi!

What is wrong with following xsl?

<xsl:template match="informaltable[@label='setup']">
	
	<xsl:apply-imports/>
	<xsl:param name="informaltable.frame.border.thickness" select="'3.0px'"/>
	<xsl:param name="informaltable.frame.border.color" select="'green'"/>
	
</xsl:template>

FOP dont't generate PDF at all an i'm get an ERROR-Message

"A table column must be childof fo:table, not fo:block"
