you don't say if teh input is known to be sorted, if it is (in xslt 1
 or 2)
/answers/option[last()]/@p
if the input is not known to be in the right order then (in xpath 2)
max(/answers/option/@p)

<xsl:for-each select="$nodes">
  <xsl:sort select="sort"/>
  <xsl:if test="position()=1">...</xsl:if>
</xsl:for-each>

Cheers,
Wendell
