You can use <xsl:choose> as J.Pietschmann said or you can use <xsl:if>
all depends on what you want to do with the link

The xsl:if template:
<xsl:template match="link">
 <xsl:if test="(not(@Customer) or (@Customer=$Customer)) and
(not(@Assembly) or (@Assembly=$Assembly))">
  <a href="{@urlf}"><xsl:apply-templates/></a>
 </xsl:if>
</xsl:template>

This will create a <a> node (if @Customer does not exists or if it's
value is equal to $Customer) and (if @Assembly does not exists or if
it's value is equal to $Assembly)
