Seems like you want to use xsl:choose:
  <xsl:temlate match="link">
    <xsl:choose>
      <xsl:when test="not(@Customer)">
        <a href="{@url}> ... </a>
      </xsl:when>
      <xsl:when test="@Customer=$Customer">
        <a href="{@url}> ... </a>
      </xsl:when>
      <!-- add your various combinations -->?
    </xsl:choose>
   </xsl:template>

Only the first when clause whose test evaluates to true will
be executed, so be careful arranging them. Educate yourself
about xsl:otherwise too.
