Since you don't actually need to know *how many* there are, just
whether there are any siblings of the current def or not, you could
use:

  <xsl:if test="preceding-sibling::def or following-sibling::def">
    ...
  </xsl:if>

or you could see if the def element's parent has more than one def
child:

  <xsl:if test="../def[2]">
    ...
  </xsl:if>

Cheers,
