how would I extend my basic stylesheet to incorporate the levels?

<xsl:template match="*[@type='screen']" mode="filter-condition">
	<xsl:choose>
		<xsl:when test="@userlevel='1'">
			<bullet1>
				<xsl:apply-templates/>
			</bullet1>
		</xsl:when>
		<xsl:when test="@userlevel='2'">
			<bullet2>
				<xsl:apply-templates/>
			</bullet2>
		</xsl:when>
	</xsl:choose>
</xsl:template>
