Putting a , before the and in a list is anyway a transatlantic
peversion, so in English as (usually) practiced in England 
you could lose the
     <xsl:if test="position() > 2">
       <xsl:text>,</xsl:text>
     </xsl:if>

true but in this case the vocabulary is probably fairly restricted, so a
lookup table plus a fallback case of sticking an s on the end for
anything not in the table is probably workable.
