It would involve creating a custom stylesheet. The skeleton of the XSLT can be generated with the built in  token2xsl tool. Just click on custom and generate. For further modifications, you should have a look at xslt. You will be surprised how much can be done with only a handful of functions. Here is a link to a tutorial : http://www.w3schools.com/xsl/

Armand, FnL uses normal XSL. I am not aware of any syntax like this. Can you please provide a link?

In the case for displaying both name and values I would go with a primitive <xsl:choose> approach.

For name/value pairs like A|a;b|B;c|C for a field named valuecolumn I would go with

<xsl:choose> 
  <xsl:when test="udt:valuecolumn='a'">
      A
  </xsl:when>
<xsl:when test="udt:valuecolumn='b'">
       B
  </xsl:when>
  <xsl:otherwise>
     C
  </xsl:otherwise>
</xsl:choose>
