Much clearer :) In which case you want this:

<xsl:for-each select="areaserved/district/option[@selected = 'selected']">
 <xsl:value-of select="."/>
 <xsl:if test="position() != last()">,&#160;</xsl:if>
</xsl:for-each>

Here the predicate has been moved to the select on the for-each, so
that you only select the nodes with @selected = 'selected'.
