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.
