You've had a number of solutions to this, but there is another. Assuming
this template rule is processed by <xsl:apply-templates select="def"/>
or equivalent, you can write

<xsl:template match="def">
  <xsl:if test="last()!=1">
    <strong><xsl:value-of select="concat(position(),
&#x160;)"/></strong>
  </xsl:if>
  <xsl:apply-templates/>
</xsl:template>

Using position() and last() will often be more efficient than using
count() and xsl:number, because they work on the current node list,
which you are using anyway to output the nodes.
